The photodissociation dynamics of tert-butyl nitrite at 355 nm was investigated by means of time-resolved Fourier transform infrared (TR-FTIR) emission spectroscopy. By analyzing the observed TR-FTIR emission spectra of the NO fragments, we obtained the rotational temperature and the relative vibrational distribution of NO. In addition, an inversion was found to occur within this vibrational distribution. With the aid of previous studies, we determined that the relationship between the vibrational quantum number υ of NO corresponding to its maximum vibrational distribution and the vibrational quantum numbers υ* relating to the overtone transitions of N=O stretching vibration of the parent molecule is υ=υ*-1.
