✦ Synopsis

OH stretching vibrations of jet-cooled phenol and phenol-(H*O). (n= l-3) complexes were investigated by IR-W doubleresonance spectroscopy. The stretching vibrations of the Hz0 moieties as well as that of the phenol moiety were observed for the complexes. A remarkable red-shift with increase of n was found for the phenolic OH vibration. The symmetric (vi) vibrations of the H20 moieties exhibit large red-shifts and splittings, while the antisymmetric (v,) vibrations show small red-shifts with small splittings. The spectral feature of the Hz0 moieties in the complexes was found to be quite similar to that of the pure (HsO).. The result suggests the complexes have structures such that the hydrogen bond is formed between phenol and the (HsO). clusters.
