VIBRATIONAL SPECTRA AND NORMAL COORDINATE ANALYSIS OF METHYL THIONITRITE AND ISOTOPIC ANALOGS
Byler, D. Michael,Susi, Heino
, p. 25 - 36 (1981)
The observed gas-phase IR frequencies for forty-four fundamentals of methyl thionitrite (CH3SNO) and its d3-, 13C-, and 15N-substituted analogs have been used to calculate a nineteen-parameter symmetry valence force field.The final refinement resulted in an average error of less than 4 cm-1 (ca. 0.5percent) between the calculated and observed frequencies for the four isotopomers.Contrary to earlier reports, relative intensities, isotopic frequency shifts, as well as the calculated potential-energy distribution, all support the assignment of ν(CS) to a higher frequency than that of ν(SN).For the normal molecule ν(CS) is observed as a weak band at 735 cm-1; by contrast, ν(SN) absorbs strongly at 646 cm-1.The NO stretching fundamental occurs at 1535 cm-1 in the gas-phase spectrum of the unsubstituted molecule but shifts to 1507 cm-1 when 15N replaces the normal isotope.The five fundamental bands associated with the skeletal vibrations of CH3SNO are compared with the analogous absorptions in the spectra of CF3SNO and CH3ONO.

The preparation of O-methyl S-trideuteromethyl 4,4-dithioterephthalate and S-methyl O-trideuteromethyl 4,4-dithioterephthalate is described. The EPR spectra of the corresponding radical anions are measured. Comparison with the spectrum of O,S-dimethyl 4,4
