Dye laser-induced, visible fluorescence following low-level vibrational excitation with a $CO_{2}$ laser is used to monitor the internal energy distribution under collisionless conditions ($10^{-5}$ to $10^{-3}$ torr). Time resolved spectroscopic changes in $\nu_{6}$ (C-C Stretch), the pumped mode, show that increases in population in the v=1 level follow closely the shape of the excitation pulse and that decay is exponential to 10 $\mu_{s}$. However, concomitant changes in hot bands of other modes, especially those of lower frequency, are not obvious. These results will be discussed in terms of intramolecular, V-V, and V-T energy transfer. en_US dc.format.extent 79447 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title VIBRATIONAL ENERGY TRANSFER IN PROPYNAL UNDER COLLISIONLESS $CONDITIONS^{*}$ en_US dc.type article en_US
