Abstract
Classical trajectory calculations on planar reactive collisions of H+H2 are presented and compared with previously reported quantum calculations. Probability of reaction versus impact parameter compares reasonably well for the two calculations. Classical angular distributions match the back peak of the quantum results but show no forward peak. The classical distribution of product rotational states is sharply peaked at the initial state while the quantum distribution is a very smooth function of rotational state.
