Spectroscopy, Structure and Dynamics

Our research efforts have been in the areas of Molecular and van der Waals Spectroscopy, Chemical Kinetics and Reaction Dynamics. Our main emphasis is on experimental work, though theoretical work to support and enhance our understanding is carried out as well.

We have built the first Pulsed Nozzle Fourier Transform Microwave Spectrometer in India. This is being used to study the rotational spectra of weakly bound complexes formed in a supersonic expansion. This will lead to accurate structural information that is essential in developing intermolecular potentials. Understanding intermolecular interactions is the primary goal of these studies.

Shock tube studies are being carried out, in collaboration with Aerospace Engineering Department, on the kinetics of unimolecular and bimolecular chemical reactions. Results from this work will be useful in modeling atmospheric chemistry and combustion. Also, the experimental results will be used to test and develop theories of chemical reactions.
