Abstract
Vibrational energy disposal to the CO product of the photofragmentation of 3-cyclopentenone has been studied by time-resolved CO laser absorption spectroscopy. The nascent vibrational distribution of CO is N 0 = 7.88, N 1 = 0.187, N 2 = 0.024. The measured vibrational distribution is substantially colder than that predicted on statistical grounds. This indicates that the product fragments become vibrationally decoupled from one another before the full reaction exoergicity has been released. Our results suggest that such decoupling may occur at the dissociation transition state.
