Research Interests

My major areas of interest are the dynamics of molecular collisions, the gas-surface collision dynamics, gas phase elementary reaction dynamics, and developing computational methods. The projects currently underway in my research group are the following:

Vibration of adsorbed molecules on Solid Surfaces

We have developed, and are now applying an approximate quantum mechanical theory to calculate vibrational frequencies of admolecules on a solid surface very accurately. In this method we have adapted VSCF Theory which has been used in vibrations of gas phase molecules to Gas-Surface system. In this method, vibrational eigenvalue problem is solved using the vibrational self-consistent field method, and the fundamental frequencies are obtained for a thermal distributions of hot bands. Recently, we have applied this method to the vibrational dynamics of CO molecules on Cu(100) surface.

Unimolecular Ion Dissociation Dynamics

We have developed new algorithm to construct potential energy surface for polyatomic reactions. In this method we use the energies, gradients and Hessians, which can be obtained ab initio quantum chemical calculations. The surface is constructed by interpolating the local quadratic surfaces with reaction path weights. In recently this method has applied to a five-atom reaction system,
CH2OH+ ¡æ CHO+ + H2 reaction.

Elementary Combustion Reaction Dynamics

We have developed and applied approximate quantum mechanical collision theory to elementary combustion reactions. Adiabatic approximation and Reactive Infinite Sudden Approximation in the frame work of hyperspherical coordinates have been used to investigate to oxygen involved elementary combustion reactions for calculating state to state reaction cross-sections, thermal rate constants. Recently we have applied the method to O(1D) + HCl ¡æ OH + Cl reaction.
