Abstract

Mixtures of SF6 with various simple hydrocarbons are irradiated at ≈2 torr by CO2 laser pulses of power density 108 W cm-2, yielding transient visible luminescence from products of hydrocarbon dissociation. Stepwise multiple photon excitation of SF6 molecules is shown to initiate the rapid sequence of events leading to hydrocarbon dissociation. The most probable mechanism consists of infrared photodissociation of SF6, the F atoms from which react with the hydrocarbon, yielding C2 and CH chemiluminescence.
