Abstract
The continuous absorption of carbonyl sulphide between 210 and 260 nm has been studied between 295 and 577 K. An exponential rise of absorption coefficient with temperature was found similar to the effect noted previously with nitrous oxide.1 This made it possible to justify several of the assumptions made in the earlier work and also to attribute the carbonyl sulphide continuum to transitions from bending vibrationally excited ground state molecules to a bent repulsive upper state. An electronic structure is suggested for this upper state.Keywords
