The results of an ion dip spectroscopy study of the phenol--OD [PhOD] molecule and phenol--OD(D[sub 2]O)[sub 1] [PhOD(D[sub 2]O)[sub 1]] from 500--1300 cm[sup [minus]1] are presented and the spectra compared with the undeuterated molecule and cluster. The greater modulation of the PhOD ion dip spectrum compared to that of phenol--OD [PhOH] is the result of a longer [ital S][sub 1] lifetime for the deuterated molecule due to quenching of internal conversion. The PhOD(D[sub 2]O)[sub 1] cluster spectrum allows us to identify the ground state intermolecular PhOD--D[sub 2]O stretch as 144 cm[sup [minus]1] compared to 151 cm[sup [minus]1] for the undeuterated cluster. Importantly, the blue shift of the 7[ital a][sub 1] mode (C--O stretch) provides evidence that the water acceptor molecule donates charge into the C--O bond.
