Abstract
The gas phase reaction between carbonyl sulphide and the products of a microwave discharge in molecular oxygen has been studied by electron resonance. In addition to absorption lines from O 2 and SO in their ground electronic states, a four-line pattern due to SO in its excited 1 ∆ state is observed. Analysis of this spectrum yields the rotational constant B 0 for the 1 ∆ state, from which the bond length is calculated to be 1·493 Å.
