A Diels-Alder condensation reaction in liquid phase under varying pressure conditions is modeled as a pair of coordinates, one associated with a chemical reactive motion and the other describing the accompanying contraction of the medium cavity which

A chemical reaction proceeding in a continuum medium is modeled as a pair of stochastic equations with a δ-correlated random force. A numerical method for calculating the rate constant is elaborated in a quasi-one-dimensional approximation. Exact ra

According to experimental data, gas-phase SN2 reactions have low efficiency characterized by the ratio k(T)/kc, where kc is the collision rate constant. The energy profile of the reaction pathway is a double-well curve, and the top of the central bar

The method described for constructing a curvilinear coordinate system makes it possible to investigate the dynamics of chemical reactions involving the exchange of a light atom, when the curvature of the reaction path (the reference curve) is great,

A new method has been implemented for the quantum calculation of the dynamics of exchange reactions in systems with a large curvature of the reaction path — specifically, reactions with transfer of a light atom. The method is based on the use of a

Nonempirical quantum-chemical calculations have been performed in the 4-31G basis on the equilibrium geometry and vibrational frequencies of difluorochloromethane, as well as on the transition state in the decomposition CHF2Cl→CF2+HCl. The potentia
