✦ Synopsis

The formation of the primary photoproduct (the nitronic acid) in the photo-rearrangement of o-nitrobenzylesters was investigated by time-resolved resonance Raman (lR3) spectroscopy in a polar, aprotic and polar, protic solvent. In acetonitrile, only nitronic acid is formed with a lifetime of 80 ps, whereas in methanol the nitronic acid occurs in thermal equilibrium with the nitronate anion, which has a lifetime of 100 us,
