| Research Abstract |
Pair interaction approximation (Fragment Molecular Orbital Theory:FMO) is applied for developing a quantum chemical ; program system for evaluating optical property of large molecular systems. A new functional for accounting weak force such as van der Waals is introduced Further a long standing problem of Density Functional Theory for evaluating polarizability of large molecules is resolved by introducing a long range correction in exchange functional. The non-empirical calculations are performed for evaluation of linear and non-linear optical properties of Azo-dendrimer using response theory within the FMO framework. Simple addition rule with a quantum correction between units representing partial charge transfer is found. A unified density functional theory for solvation is formulated for quantum and classical particle admixtures. The theory is successfully applied for the problems such as delocalization of excess electron in fluids, anomalous behavior of polymer chain in supercritical solvents and an remarkable increase of positron annihilation rate in supercritical fluid.
