✦ Synopsis

The use of collinear-type hyperspherical coordinates to investigate three-dimensional light-atom transfer reactions within the framework of the adiabatic approximation (with respect to rotational motion) originally devised by Bowman is proposed. In the cases of (I ) synimetric light-atom transfer and (2) near-resonant asymmetric light-atom transfer reactions, explicit approximate analytical expressions available for collinear reaction probabilities are suggested to estimate directly the three-dimensional reaction cross sections and rate constants. It is also demonstrated that the Rosen-Zener formula is applicable to collinear asymmetric light-atom transfer reactions without introducing any diabatic representation of potentials.
