Bar Ilana: Probing dynamics and structure of molecules using laser spectroscopy
area of active research is the study of dynamics, structure and bond
cleavage in gas phase molecules utilizing pulsed lasers. These
characteristics are probed via spectral signatures of the species with
various spectroscopies, employing tunable lasers spanning the infrared,
visible and ultraviolet regions of the spectrum. In particular, we seek
for the possibility of controlling bond fission via energy deposition
in different skeletal motions of molecules. The major goals are to find
ways for selecting desired reaction pathways, for altering state
distributions, for developing an understanding regarding vibrational
energy flow within molecules, and for finding non-statistical behaviour
so that it can be predicted and may be even controlled by lasers.
Another research project involves the development of a new
spectroscopic method for the study of floppy biomolecules. This is due
to the crucial role that conformations and shapes of molecular
constituents involved in biological processes play in determining their
selectivity and functionality. The exploration of these properties is
thus a prerequisite for gaining molecular-level understanding of the
complex dynamics of these processes. Structures and interactions of
biomolecules are of fundamental importance in elucidating the
mechanisms of biological processes and might have implications on
designing drugs that mimic, activate or suppress the function of
