Research Interests |
Experimental
chemical physics.
Studies
of molecular dynamics
by laser and spectroscopic
methods. Laser-induced
fluorescence studies
of vibrational
energy transfer
processes; the
role of sensitizers
in laser-stimulated
chemical reactions;
solvent-solute
interactions by
magnetic resonance
techniques; dynamics
of transient complexation.
Laser
studies - gas
phase.
Infrared
laser pulses
provide rapid,
selective excitation
of specific
molecular states
or species.
Rates and mechanisms
of reestablishing
equilibrium
are determined
by monitoring
time-dependent
fluorescence
from specific
molecular levels.
Recent work
has examined
the selectivity
of interspecies
vibrational
energy flow
processes and
the theory
of long-range
interactions.
Current goals
of the research
are: 1) to
understand
the importance
of different
energy transfer
mechanisms
in governing
relaxation,
heating, and
reaction processes;
2) to examine
the collision-induced
coupling between
molecules excited
to states above
the discrete
levels; 3)
to improve
and test theories
of long-range
vibrational
energy transfer;
and 4) to examine
on a molecular
level the role
of absorbing
media in the
laser cavity
in inducing
instabilities
and chaotic
behavior in
the laser output.
Magnetic
resonance studies
- liquid phase.
Intermolecular
couplings of
nuclear and
unpaired electron
spins probe
the dynamics
of molecular
interactions
in liquids.
Transient population
shifts are
used to examine
molecular structure
and its sensitivity
to interactions
with other
species in
solution. The
objectives
of this program
are to identify
the time and
distance parameters
that characterize
short-lived
interactions
between molecules,
to probe on
a molecular
level the effect
of the solvent
on interactions
such as hydrogen
bonding, and
to detect differences
in accessibility
of sites on
molecules for
forming short-lived
complexes. |
