For the treatment of equilibrated molecular systems in a heat bath we propose a transition state theory that is based on conformation dynamics. In general, a set-based discretization of a Markov operator P does not preserve the Markov property. In this article, we propose a discretization method which is based on a Galerkin approach. This discretization method preserves the Markov property of t...

This paper is a density functional theory (DFT) calculation of intramolecular proton transfer (IPT) in 6-hydroxypicolinic acid (6HPA, 6-hydroxypyridine-2-carboxylic acid) tautomeric forms. The transition state for the enol-to-keto transition is reported in the gas phase and in four different solvents. The planar and non-planar dimer forms of 6HPA keto and enol, respectively, were also studied i...

the reaction mechanism between (h2c) and (7, 0), zigzag single-walled carbon nanotubes(zswcnts) on two different orientation of c-c have been studied by semi empirical am!method. the activation barriers of (h2c) adding to (7, 0) zswcnt are computed and compared.the effects of diameters of zigzag swcnt on their binding energies were studied

A theoretical study of the kinetics and mechanism of second-order intermolecular C.) cloadd it ion of 2-Ethyny1-2,3-Dihydrofurane and Phenyl Azide was performed using DFT method at 101.111 le) cl of theory with 6-31 PrEG(d,p) basis set at 298.15K. Equilibrium molecular geometries and harmonic ) ihrational frequencies ofthe reactants, transition state, and product were calculated. The kinetic an...
