Volatile thiols are easily and almost unerringly detected by their distinctive odor. Sulfur-specific analyzers for gas chromatographs are useful. Spectroscopic indicators are the D2O-exchangeable SH signal in the H NMR spectrum ( S is NMR-active but signals for divalent sulfur are very broad and of little utility ). The νSH band appears near 2400 cm in the IR spectrum. In the nitroprusside reaction, free thiol groups react with sodium nitroprusside and ammonium hydroxide to give a red … WebNov 9, 2024 · New infrared spectra are presented for H 2 S and four other sulfur-containing compounds, all thiols, at 10–140 K to aid in the study of interstellar and solar system ices.
