Abstract
Stimulated emission pumping spectra of HFCO in a pulsed jet at 0.2 cm−1 resolution in the range of 13 000 to 23 000 cm−1 are reported. Above the dissociation threshold, ≊14 000 cm−1, linewidths vary from 0.15 to 2.0 cm−1 for S0 vibrational levels within an energy range of a few hundreds of cm−1 . Substantial vibrational mode dependence of intramolecular vibrational energy redistribution and/or dissociation rates is likely.Keywords
