Abstract
The fundamental and the first overtone of the OH stretching vibration of isopropanol and tertiary butanol were measured in solution at temperatures ranging from -- $40^\circ$ to -$-180^\circ C$. Solvents were used which form rigid glassy media at liquid nitrogen temperature. The changes in the frequency, band-width and anharmonicity over this range of temperature are discussed. The role of anharmonicity in the observed shift upon hydrogen bond formation is emphasized. Two bands appear in the first overtone region, one of which is shown to be due to simultaneous excitation by one vibrational quantum in two OH groups linked together by hydrogen bonding.
