The FTIR spectrum of the unstable species thioketene, CH2CS, has been detected in a vapor-phase flow pyrolysis system. The region 800-3500 cm-1 has been surveyed with a resolution of 1 cm-1, enabling the frequencies of the six fundamentals which lie above 800 cm-1 to be determined. Certain bands have been studied under very high resolution and the results of the analyses of the perpendicular bands ν7 and ν3 + ν8, observed with a resolution of 0.01 and 0.005 cm-1 respectively, are presented. The ground state constant, A0, is determined as 286 453.60(58) cm-1.
