Abstract
The dynamics of energy dispersion in propynal has been studied over the pressure range of 5 to 500 mtorr following excitation by a TEA CO2 laser below the dissociation threshold. Wavelength resolved spectra, using the dye laser-induced fluorescence technique, are used to characterize the vibrational levels that are involved in the various energy transfer processes, while time-resolved spectra are used to determine the corresponding rates. The rate constants are extrapolated to zero pressure to obtain the regime of collisionless intramolecular relaxation times. Mechanisms of energy dispersion involving each of the probed vibrational levels (v = 0), ν6(v = 1), ν9(v = 1), and ν4(v = 1)) are discussed.
