“Don’t dream it, be it.”
Richard O’Brien ‐ The Rocky Horror Picture Show (1975)
“Another turning point, a fork stuck in the road.
Time grabs you by the wrist, directs you where to go.
So make the best of this test, and don't ask why.
It's not a question, but a lesson learned in time.
It's something unpredictable, but in the end it's right.
I hope you had the time of your life.”
Green Day ‐ Time of Your Life (1997)

This thesis would not have been possible without the help of many people. I would like to
thank all of them for their outstanding efforts, work, help, patience, care, and supervision.
You all have a big stake in my success.
Prof. Dr. Martina Havenith‐Newen supervised me during my Bachelor’s, Master’s and PhD
thesis. I would like to thank her for all the trust she put in me, for her patience and
competent supervision, and for giving me the opportunity to do high‐level research in such a
stimulating atmosphere. Also, I would like to thank her for letting me take part in other
projects besides my thesis.
Prof. Dr. Hermann Weingärtner is my second examiner and cooperation partner. Thank you
for providing the microwave dielectric spectra, for help with the data interpretation and for
kicking off the ionic liquids project.
Prof. Dr. Martin Hofmann is my second supervisor according to the Individual Training and
Supervision Plan (ITSP) of the Research School. Thank you for much advice and help and for
being the lecturer and examiner of my minor class exam.
I would like to thank Dr. Erik Bründermann for excellent guidance, outstanding competence
and supervision. Thank you for always being straightforward and supporting me. Moreover, I
would like to thank him for letting me take part in many of his interesting projects. I wish I
were able to give him back at least a little percentage of what he has given to me. Thank you
Erik also for proof‐reading this thesis.
Many thanks go to Asst. Prof. Dr. Özgür Birer, Dr. Rajib Mitra, Dr. Diedrich Schmidt and Dr.
Gerhard Schwaab for experimental help, proof‐reading, many fruitful scientific discussions
and support with the data analysis.
I would like to thank Prof. Dr. Martin Gruebele and Dr. Seung‐Joon Kim for letting me
participate in the development of the Kinetic THz Absorption (KITA) experiment.
Thank you to Prof. Dr. Wim van der Zande and Dr. Afric Meijer from Radboud University ‐
Nijmegen for cooperation and scientific exchange. viii Acknowledgements
I would like to thank Prof. Dr. Martin Thomas Zanni, Dr. Terry Ding and all other members
of the Zanni group at the University of Wisconsin ‐ Madison for the introduction to 2D‐IR
spectroscopy and three exciting months in the US. I also acknowledge the funding of this
research visit to the Foundation of German Economics (SDW).
Thank you to Prof. Dr. Uwe Weidner and Dipl.‐Ing. Sulamith Frerich for letting me take part
in a nice cooperation project on micro‐particles and for giving me an insight into state‐of‐
the‐art research on process engineering.
Thank you to Dr. Nils Gerhardt and Dr. Stefan Hoffmann for instant and useful help with
diodes, fibers and other optical and photonic devices.
I would like to thank Prof. Dr. Anja‐Verena Mudring and her group for carefully synthesizing
some of the ionic liquids and for fruitful discussion meetings.
Thank you to M.Sc. Mianmian Huang for help with the preparation and drying of the ionic
liquids and for providing the microwave dielectric spectra.
Thank you to Dr. Christop
