The high-resolution infrared spectra of the acetylenic C-H and O-H stretches of propynol have been measured using an electric-resonance optothermal molecular beam spectrometer (EROS). Both spectra display extensive fragmentation of the hydride-stretch oscillator strength characteristic of the intramolecular vibrational energy redistribution (IVR) process. The IVR Lifetime is strongly mode-specific. The IVR lifetime of the acetylenic C-H stretch is approximately 400 ps, with a slight increase in the Lifetime with increasing values of the K-a quantum number. The lifetime of the O-H stretch is 60 ps and is independent of the rotational quantum numbers. The experimental upper limit for the anharmonic state densities are 30 and 40 states/cm(-1) for the acetylenic C-H and O-H stretches, respectively. These values are in good agreement with the values obtained by a direct state count (19 and 32 states/cm(-1), respectively). The measured density of states increases with an approximate (2J + 1)-dependence. These results indicate that all energetically accessible states are involved in the IVR dynamics. However, neither the acetylenic C-H nor the O-H stretch shows a decrease in Lifetime as the total angular momentum (J) increases. This result shows that Coriolis coupling of these two hydride stretches to the near-resonant bath states is much weaker than the anharmonic coupling. For the O-H stretch, we are able to obtain the root-mean-squared (rms) matrix element for the Coriolis coupling prefactor, 0.0015(5) cm(-1). The rms anharmonic coupling matrix element is 0.03 cm(-1). For the low J values measured in the O-H spectrum, the Coriolis-induced NR rate is much slower than the initial redistribution rate resulting from the stronger anharmonic interactions leading to an IVR process with two distinct time scales.
