Work Group Prof. Dr. F. Temps

Over the years, we had the pleasure of visits by a number of distinguished guest scientists, colleagues and friends:

Dr. Xiaonan Ma (State Key Laboratory for Molecular Reaction Dynamics, Chinese Academy of Sciences, Beijing)

Xiaonan  received his Ph.D. in the summer of 2011 from the Institute of Chemistry, Chinese Academy of Sciences, where he worked on femtosecond studies of ultrafast photoinduced intra- and intermolecular dynamics, including chromophore-chromophore couplings and ionic liquids. He joined our group at CAU Kiel for two years starting in February 2013 with a prestigious Alexander von Humboldt fellowship. His work plan includes femtosecond studies of the dynamics of excited-state intra- and intermolecular proton or hydrogen atom transfer reactions and coherent energy transfer involving exciton states in multichromophoric molecules. Both projects complement our activities in the CRC 667 "Function by Switching".

  

Prof. Dr. Hu Changjin (Wuhan Institute of Physics and Mathematics, Chinese Academy of Sciences)

Changjin visited Kiel from January to April 2008 within our exchange programme. He was involved in femtosecond transient absorption and in photofragment imaging measurements, where his experience in DC slice imaging was very helpful.

  

Dr. Yanmei Wang (Wuhan Institute of Physics and Mathematics, Chinese Academy of Sciences)

Yanmei worked in Kiel for three months (September - November 2007) within our exchange programme with Wuhan to do femtosecond TOF/MS measurements on penta- and hexafluorobenzene. She was in Kiel before in 2006, shortly before she obtained her Ph.D. back in Wuhan.

  

Dr. Song Zhang (Wuhan Institute of Physics and Mathematics, Chinese Academy of Sciences)

Song Zhang has been awarded an Alexander von Humboldt fellowship for two years starting in December 2006. He previously visited us within our exchange programme with Wuhan.  He is working with us in Kiel on femtosecond time-of-flight mass spectrometry and photoelectron imaging of a series of fluorobenzenes and pyrrole derivatives.

  

Prof. Dr. Bing Zhang (Wuhan Institute of Physics and Mathematics, Chinese Academy of Sciences)

We are happy to have a long-term collaboration, started in 2006, with the group of Professor Zhang from the Wuhan Institute of Physics and Mathematics, Chinese Academy of Sciences, funded by the German Academic Exchange Agency (DAAD) and China Scholarship Council (CSC).  In our Joint German-Chinese Research Project, we are study the Radiationless Relaxation, Isomerization, and Dissociation Dynamics of Electronically Excited Molecules by Femtosecond Time-of-Flight Mass Spectrometry and Photoelectron Imaging. Since 2006, we have had several Ph.D. students and postdocs from Bing's lab visiting us at Kiel for periods up to three months, working on different femtosecond experiments. Likewise, several Kiel group members have visited Wuhan, where they were involved in photofragment imaging experiments.  Bing Zhang first visited Kiel in the spring of 2006.  He will be back next time in the fall of 2007 and again in 2008.

  

Dr. Stig Rune Sellvaag (Oslo University)

Stig was a Ph.D. student in Claus Nielsen's group at Oslo university working on atmospheric chemistry. He is interested in the atmospheric oxidation of HFC's and their products. He visited Kiel thanks to support by the Nordic Network for Chemical Kinetics (NoNeCK) in September 2003 to carry out product measurements after photolysis of trifluoroacetaldehyde and other fluorinated carbonyl compounds using our FTIR spectrometer, experiments which are complementary to the work he was doing in Claus group in Oslo.

  

Dr. Yuanqing Guo (Wuhan Institute of Physics and Mathematics, Chinese Academy of Sciences)

Yuanqing Guo received his Ph.D. from Wuhan in early 2001. His thesis was concerned with MIR-LMR spectra of NO and NO2. He came to Kiel in July 2001 and brought our FIR-LMR spectrometer back into business. Another project Yuanqing has been working on was cavity-ring-down spectroscopy of Si containing radicals and the kinetics of SiH2 reactions. He developed a new quantitative method to include the laser bandwidth effects in the analysis of simultaneous chemical kinetics and ringdown decay profiles.

  

Dr. Jie Wei (Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences)

Jie Wei has been awarded an Alexander von Humboldt research fellowship to work in Kiel for two years starting in April 2001.  He was involved in our unimolecular dynamics experiments, especially the investigations of product state distributions from the quantum state specific unimolecular dissociation of, e.g., HCO and DCO using time of flight mass spectrometry and velocity map ion imaging. He also performed new experiments on H and D atom eliminiation from pyrrole and pyrrole-d1 which appear to proceed via conical interesections. His results shed a new light on the radiationless deactivation processes of heteroaromatic molecules of biological interest, including the nucleobases.

  

Dr. Vladimir Markov (Russian Academy of Sciences, Nizhnii Novgorod)

Vladimir has been a frequent visitor to Kiel. He has previously been working with A. Guarnieri and H. Mäder. He joined us in the second quarter of 2001, working with our Molecular Beam - Fourier-Transform Microwave (MB - FTMW) spectrometer with the intention to look at spectra of free radicals, namely CCl2, CFCl, CHCl, and CHBr. Vladimir helped to improve the detection sensitivity of our spectrometer. He will be back in Kiel in 2002.

  

Dr. Helmut Beckers (Inorganic Chemistry, University of Wuppertal)

With Helmut Beckers, we investigated small unstable inorganic molecules,which can be generated by flash pyrolysis. Precursor molecules were synthesized by Helmut and brought to Kiel, where we tried to record and analyze FTMW spectra. This project was supported by the DFG-Schwerpunkt "Si chemistry".

  

Dr. Gleb Eshchenko (Institute of Chemical Physics, Russian Academy of Sciences, Moscow)

Gleb has been visiting Kiel from January 2001 until the end of 2002. He was interested in the kinetics of elementary reactions in the NOx-reburning mechanism by time-resolved direct techniques. His experiments involved excimer laser flash photolysis of CH2CO in a tubular flow reactor coupled to a mass spectrometer. The challenge will be to reach high temperatures up to 1300 K. He has also been involved in our work on silane reactions.

  

Dr. Kristina Imrik (Chemical Research Centre, Budapest)

Kristina visited Kiel in early 2000, doing experiments on the kinetics of oxygen containing hydrocarbon radicals (CH3CO, CH3COCH2) and on the photodissociation mechanism of acetyl acetone.  Her visit was part of our ongoing collaboration under the auspices of the Hungarian - German Intergovernmental Science and Technology Cooperation Programme.

  

Dr. Akos Benscura (Chemical Research Centre, Budapest)

Akos spent a period of six weeks in Kiel (November to December of 1999).  He was involved in our studies of the SiH3 oxidation kinetics with the laser photolysis - flow tube - quadrupole mass spectrometer combination. He also assisted in the set-up of a long path UV absorption cell.  Akos came back to Kiel in 2000.

  

Dr. Bernd Abel (Universität Göttingen)

Bernd spent a few days in Kiel in the summer of 1999 for the preparation of a microwave - UV double resonance experiment on NO2. 

  

Prof. Dr. Sandor Dóbé (Chemical Research Centre, Budapest)

Sandor has been a dear friend and frequent visitor since the good old Göttingen days.  He is becoming a frequent visitor to Kiel now, thanks to the Hungarian-German Intergovernmental Science and Technology Cooperation Programme. Our mutual interests are in the study of the oxidation kinetics and dynamics of oxygen containing hydrocarbon radicals with relevance to atmospheric chemistry and combustion.

  

Dr. Erko Jalviste (Tartu University, Estonia)

Erko is a regular visitor to Kiel, most recently in November/December 2011.  He first joined us as Alexander von Humboldt Research Fellow.  He spent one and a half years in Kiel in 1997/1998, another half a year in early 2001, and a few monsths in 2004.  He worked on the laser induced fluorescence of jet-cooled indazole.  He successfully measured the excitation and dispersed fluorescence spectra of indazole monomer and indazole-water complexes and managed to analyze the spectra with the help of ab initio calculations.  He had the courage and he had the patience to sort through long series of spectra - which at first glance looked quite horrible, but in the end were very rewarding.  Erko has recently carried out hole-burning experiments on the dimers and trimers of indazole and various complexes of indazole with water and measured their REMPI spectra.

  

Prof. Dr. Mike Pilling (University of Leeds)

Mike Pilling spent one week in Kiel during the "Kieler Woche" sailing events in 1997.  He gave talks on atmospheric chemistry and on unimolecular reactions.
