Notes:
The resonance Raman spectra of S-methyldithizone (MeHDz), S-ethyldithizone (EtHDz) and S-isopropyldithizone (iPrHDz) have been measured in the solid state and in solution. It is shown that the red and yellow isomers of these S-alkyldithizones adopt in solution the trans-syn-s-trans and trans-anti-s-trans configurations, respectively, with respect to the N=N, C=N and C—N bonds of the formazan skeleton. It is also demonstrated that for EtHDz the red and yellow isomers can be isolated as different crystal forms. Vibrational assignments are given for both red and yellow isomers of MeHDz based on the frequency shifts of five kinds of isotopically substituted species.
