Abstract
Propargyl alcohol is an interesting molecule for the study of intramolecular vibrational dynamics. In particular, there is a low frequency, large amplitude torsional motion. We have reinvestigated the low frequency region of the spectrum (20-120 GHz) and find that the two lowest torsional levels are in coriolis resonance. We have also measured the $C-O$ stretch normal mode region around $1040 cm^{-1}$ using the $CO_{2}$ sideband system and EROS spectrometer. Using a weak expansion in He we find that the two lowest torsional levels are nearly equally populated giving us spectroscopic characterization of both in the $9\mu$m region.
