Interaction-induced infrared (IR) absorption bands for H{sub 2} dissolved in liquid water at room temperature are reported for the first time. The {ital Q}{sub 1}(1) absorption band present in aqueous solution is compared to those observed for the same gas dissolved in CCl{sub 4} and in mixtures of CCl{sub 4} with acetonitrile. The analysis of the observed bands together with available information about the effect of electric fields on the integrated absorption of this normally forbidden band give an estimated maximum value for the local electric field on the solute molecule due to the solvent dipole moment. The results suggest that the electric field-induced dipole on H{sub 2} dissolved in water is very small compared to that induced in low density H{sub 2}--H{sub 2}O gaseous mixtures.
