Abstract
THRUSH1 has reported on the apparent heterogeneity of initiation of reaction in gaseous mixtures of acetylene and oxygen sensitized by nitrogen dioxide, when flash photolysis was used to produce a region of homogeneous chemical reaction. The techniques of using flash photolysis to initiate explosions of hydrocarbon–oxygen–nitrogen dioxide systems are well known2,3. This apparent heterogeneity has been explained by the appearance of detonation waves over very small distances. It occurred to me that flash photolysis might be used to initiate detonation waves of certain geometries in a current detonation and shock-wave shaping programme in this laboratory.
