Two-dimensional reaction model of Trakhtenberg et al. [19] and Siebrand et al. [22].
Two-dimensional reaction model of Trakhtenberg et al. [19] and Siebrand et al. [22].
In this model the motion of the heavy hydrogen carrying (A) and hydrogen accepting (B) atomic groups is taken into account. By these low frequency motions the crossing of the potentials, i. e. the barrier height and width is strongly modulated even at very low temperatures.
