The generation and vibrational spectrum of matrix isolated thioformaldehyde and dideuterothioformaldehyde

Abstract

The photolysis of inert matrix isolated methylene trithiocarbonate at 10 K has been shown to be a clean source of thioformaldehyde. The CH2S and CD2S molecules produced this way are indefinitely stable under these conditions and their FTIR spectra could be recorded. A normal coordinate analysis has been carried out and all the normal frequencies of both molecules have been assigned.
