Photoacoustic Raman spectroscopy (PARS) is shown to be a sensitive technique for obtaining Raman spectra of hydrogen-bonded complexes in the gas phase. Coherent anti-Stokes Raman spectroscopy (CARS) provides analogous spectra in supersonic expansions. The effective resolution is higher in the latter case due to the cooling and collision-free conditions in the jet. The ability to "tune" complex size by changing expansion conditions is demonstrated in the case of HCN.
