Infra-red chemiluminescence from vibrationally excited CO. Part 1.—The reaction of atomic oxygen with carbon disulphide

Abstract

Infra-red chemiluminescence from the reaction between atomic oxygen and carbon disulphide arises almost entirely from vibrationally excited CO. Evidence is presented which demonstrates conclusively that CO is excited in the reaction; O + CS →CO + S; the rate constant for this reaction at room temperature is estimated to be 1.4 × 10^–11 cm³ molecule^–1 s^–1.
