## Abstract At temperatures of 356‐425°C and pressures of 15–60 Torr, cyclopropylamine reacts to give an equimolar mixture of ammonia and N‐propylidenecyclopropylamine as the initial product. The reaction is first order, homogeneous, and unaffected by the presence of radical inhibitors, and thus pr

✦ Synopsis
Abstract
The high‐pressure isotopic rate ratio k~H~/k~D~ for isomerisation of cyclopropylamine and cyclopropylamine‐N‐d~2~ is 1.06 at 649–678 K, supporting a mechanism which does not involve migration of hydrogen from the amine group in the rate‐determining step.

## Abstract The carbon kinetic isotope effect in the reaction of CH~4~ with OH has an experimentally measured value of 1.003. The measurement was performed using a static system in which the source of OH was the gas‐phase photolysis of H~2~O~2~ with ultraviolet light produced by a high‐pressure mer
