✦ Synopsis

A method for the calculation of rate constants of bimolecular reactions for an arbitrary type of spherically isotropic transfer probabilities and the interaction potentials between reagents has been developed. On the basis of this method, an integral representation of upper and lower bounds for quenching radius is proposed. It has been shown that a relative deviation of the upper from the lower estimate cannot exceed 20%. Comparison with the available analytical results shows good accuracy of the approximations in the description of the viscosity dependence of quenching radius.
