Coulomb Explosion Imaging (CEI)

CEI technique offers to image an instantaneous structure of a single molecule. By Coulomb-exploding a large number of molecules in the gas phase, one can image the square of the wave function without having any beforehand knowledge of the system. 

Slow ion induced Reactive Scattering

This is a long-term goal of our laboratory. The project aims to investigate the ion collision-induced reactive scattering of different small to medium sized molecules (including polycyclic aromatic hydrocarbons (PAHs) and biomolecules) to provide a comprehensive understanding towards the stability of these systems. Here, we aim to study a range of kinematical problems regarding the charge transfer, proton transfer, collisional energy transfer, hydrogen abstraction, and dissociation of the molecules in the gas-phase using a crossed-beam ion imaging technique. 

For this project we also collaborate with University of Innsbruck.

Highly charged ion (HCI) induced fragmentation of small molecules

Here, we will mostly perform collaborative research work with TIFR, Mumbai. The main idea of these studies are to understand the highly charged ion induced fragmentation dynamics of atomic and small molecular systems.

Femtosecond laser-molecule interactions

We also plan to pursue femtosecond laser induced studies for relatively small molecular species. Especially, the femtosecond laser-based studies will be performed using the existing femtosecond laser system in IISERB. Some of targeted research problems are listed below:

1) N-body dissociation of molecular ions, 

 2) Understanding Molecular Chirality using Laser light, 

3) Studying the structure and wavefunction of Molecules via Coulomb explosion.
