Characteristic mass spectroscopic data for the identification of ten nitrosophenols is presented. The use of TMS derivatives for gas chromatography‐mass spectrometry of 4‐nitrosophenols is discussed, together with the use of copper chelates for obtaining direct insertion spectra of 2‐nitrosophenols. The fragmentations of nitrosopher ols also show ions derived from their quinonemonoxime tautomers, even under gas chromatography‐mass spectrometry conditions, indicating that isomerization occurs in the mass spectrometer. An anomalous elimination of nitrogen from these nitrosophenols has been shown to be a facile reduction of the nitroso moiety which takes place in the ion source of the mass spectrometer.
