Foreword


The work of this thesis has been carried out from December 2000 to July 2004 at the
Institute of Physical and Theoretical Chemistry of the Johann Wolfgang Goethe University
Frankfurt am Main in the research group of Prof. B. Brutschy.
I would like to thank everyone who contributed to this work.
To PD Dr. Christoph Riehn for being my Doktorvater, for his remarkable supervising and
invaluable help in every stage of my PhD studies.
To Prof. Dr. Bernhard Brutschy for giving me the opportunity to work in his excellent
research group. I gratefully acknowledge his contribution to and support of this work. His
ideas gave inspiration to explore new aspects and applications of fs DFWM spectroscopy.
I thank my dear friend Dr. Maxim Gelin (Minsk, Belarus) for his excellent cooperation in
various projects, continuous support in the spectral simulation theory and his optimism.
I am grateful to Prof. Dr Włodzimierz Jarz
ba † (Krakow, Poland), for his help in the
setting up the fs DFWM experiments. I grieve deeply for his sudden death from cancer.
I thank Dr. Daniil Kosov for our many discussion, which provided me with help and
motivation, and for his worldly wisdom.
I am grateful to Prof. Dr. Peter Hering (Universität Düsseldorf) for lending a gas cell and
introducing to the technology of heat pipes.
I am thankful for significant contributions to the development of the laser system, electronic
and vacuum setup by the following people: Dr. Andreas Weichert for optimizing the laser
system, Dr. Alfred Steiger and Martin Engels for their help with electronic devices of the
experimental setup.
I am obliged to Prof. Pavel Hobza (Prague, Czech Republic), Dr. P. Tarakeshwar and Prof.
Kwang S. Kim (Pohang, Korea) for support with ab-initio calculations, to Prof. P. M. Felker
(UCLA, USA) for providing his RCS computer code.


Many thanks to the former and present members of the research group of prof. B. Brutschy
for their help, advice and good working atmosphere. In particular, Dr. Hans-Dieter Barth,
Dr. Bernd Reimann, Dr. Michail Lebedev, Dr. Oliver Krauss, Nina Morgner, Sascha
Vaupel, Michael Barashkov, Fuat Altunsu, Barbara Kirchner, Peter Richter.
Finally, I would like to acknowledge my wife Olga and my son Zhenya for their love, care
and support during these years.
