Abstract

Analysis of the variable temperature $^1H$ and $^{13}C$ and ambient temperature $^2H$ NMR spectra coupled with IR spectra of S-methyl dithiocarbazate shows that the results can be best rationalized in terms of a mixture of cis-cis and trans-cis conformers. The assignment of the proton chemical shifts has been supported by utilizing lanthanide induced shifts. The torsional barrier about the $C\- N$ bond has been determined; a full line shape analysis of the $^1H$ spectra at different temperatures has been made. The rotational behaviour in the $N$-protonated form relative to the free base is also noted.
