Resonance enhancement of the NO stretching Raman bands has been observed from dilute solutions (10 −3 ‐10 −2 mol dm −3 ) of some alkyl nitroxyl radicals by excitation into their ultraviolet absorption band (λ max ≈ 240 nm). Excitation at 248 nm was produced by a line‐narrowed, pulsed KrF excimer laser. Three overtone bands, which were observed for di‐ tert ‐butylnitroxyl, showed a small anharmonic contribution, x e ν e = 8.8 cm −1 .
