Abstract
ΔM8 = ±2 transitions of benzophenone, p-hydroxybenzophenone, p-methyl-benzophenone, p-aminobenzophenone, benzyl, xanthane-9-one, fluorene-9-one, and thio-xanthane-9-one in EPA glass at 77 K were observed with a fast-scan flash-synchronized X-band ESR spectrometer. Instrumentation which may be useful in the observation of ΔM8 = ±2 transitions in similar short-lived S≠O molecules is discussed.
