Abstract

Vibrational data for five carbonyl isothiocyanates X CO NCS, with X F, Cl, Br, MeO and EtO, and for acetyl isothiocyanate CH3 CO NCS are reported. Detailed assignments for the infrared and Raman data of the-F,-Cl and-CH3 species are given. The vapour phase IR spectrum of acetyl isothiocyanate suggests the presence of the cisoid conformer only but the spectra of all the carbonyl isothiocyanates show features which are interpreted in terms of ...
