Abstract
Dynamics of the HD2O+ formation in the reaction of D2O+ and NH3 was investigated in a crossed-beam scattering experiment. At T = 1·5 eV (c.m.) the product is formed simultaneously by two different collision mechanisms, by a direct H-atom transfer and by the decomposition of an intermediate complex (D2O.NH3)+; the probabilities of the two mechanisms are about equal at this collision energy. The scattering makes it possible to suggest that in the critical configuration the intermediate complex is a prolate, near-linear species D2OH+.NH2.
