โœฆ Synopsis

The dynamics of the reaction of P' with methane were studied by means of a combination of an approximate classical trajectory method and RRKM theory, using accurate ab initio computations of the relevant minima and saddle points of the lowest singlet and triplet potential energy surfaces. The results were compared with those of gas-phase experiments obtained at 300 K. Computed rate coefficients are given for a wide range of temperatures from 40 to 1OOOK and may be useful in the modelling of interstellar chemistry, where the reaction of P' with methane is believed to play a crucial role in the synthesis of small molecules containing a P-C bond. The results appear to imply that an intersystem crossing process may play a key role in the reaction dynamics.

The activation energy and optimized transition-state geometry for the abstraction of a hydrogen atom from methane by methyl radical have been calculated by the semiempirical methods MIND0/3 and MNDo. These results are compared with other semiempirical and ab initio results. The MINDO/3 method, based

A theoretical study was performed for the reaction of formyl cation and acetylene to give C 3 H + 3 + O in flames and C 2 H + 3 (nonclassical) + CO, both in flames and in interstellar clouds. The corresponding Potential Energy Surface (PES) was studied at the B3LYP/cc-pVTZ level of theory, and singl

## Abstract A direct dynamics method is employed to study the kinetics of the multiple channel reaction CH~3~OCl + Cl. The potential energy surface (PES) information is explored from __ab initio__ calculations. Two reaction channels, Clโ€ and Hโ€abstractions, have been identified. The optimized geome
