Signatures of Flexible Biomolecules"
The structure of biomolecules plays an important role in determining
their selectivity and functionality. Molecular shapes and conformations
of gas phase biomolecules are mostly investigated by coupling infrared
(IR) excitation of fundamental vibrational modes with resonant two
photon ionization (R2PI) in the ultraviolet (UV). However, due to the
lack of tunable laser sources in the entire IR region, spectral
features can be monitored only in a limited range. Therefore, we
develop and employ, for the first time, a method combining Stimulated
Raman Excitation (SRE) with ion dip spectroscopy (IDS) to investigate
and map conformations of small biomolecules. Our results show the great
potential of the ILSRS technique, for obtaining the spectral
signatures of biomolecules, while using available laser sources.
