A re-examination of the structured near-UV electronic absorption spectrum of gaseous CH3ONO has revealed that previous assignments of the vibronic origin and of the prominent progression in the excited-state N=O stretching vibration are insecure. An alternative assignment that is in better agreement with the observed spectra and their temperature dependence is presented.
