Abstract
The population distributions of the rotational quantum states of the nascent MgH(v=0 and 1) produced in the reaction of Mg(3s3p 1P1) with H2 are bimodal. With the use of the surprisal method, the two components are separated. The minor low-N component of the distribution in the v=0 state is found to be larger than that in the v=1 state, whereas, the major high-N component of the distribution in the v=0 state becomes roughly equivalent to that in the v=1 state. The two parallel low-N and high-N processes are expected to correspond to two distinct types of reaction dynamics. One (minor) type produces MgH in lower rotational levels and preferentially v=0, and the other (major) type produces MgH in higher rotational levels with comparable v=0 and v=1 populations. Possible dynamical models are discussed. © 1994 The American Physical Society.
