Wj. Balfour et al., THE INFRARED AND RAMAN-SPECTRA OF METHOXYCARBONYL AND THIOMETHOXYCARBONYL ISOCYANATES, Canadian journal of chemistry, 71(10), 1993, pp. 1627-1631
The gas phase infrared and liquid phase Raman spectra of the title com
pounds have been recorded and vibrational analyses performed. The spec
tra show evidence for the presence in both the liquid and vapour phase
s of two rotational isomers: cisoid-Z and transoid-Z with reference to
orientation of isocyanato and methyl groups relative to the carbonyl
group.
