We studied the photodissocation dynamics of methyl nitrite excited to the S₁ and S₂ states by rediscovering the resonance enhanced multiphoton ionization of the CH₃O photofragment. While the NO photofragment's state distibutions are well known, the state distributions in the methoxy had not previously been determined.
