Laser Spectroscopy of Helium Solvated Clusters of Methanol and Methanol-Water in the Symmetric Methyl Stretching Band.

Mid-infrared spectra of methanol and methanol-water clusters have been investigated in the symmetric CD stretching band of CDOH and CDOD. We find that the position of this band provides a useful signature of the general type of hydrogen-bonded cluster it is associated with. Our results are consistent with those previously reported in the OH stretching region (Sulaiman, M.
