Abstract: The IR spectra of hexafluoroisopropanol were studied in the gas phase at 300 K and in liquefied xenon in the temperature range of 165–190 K. The positions and relative intensities of the bands of the first and second overtone of the $\nu$(OH) stretching vibration were measured. Calculations performed using the Gaussian package confirm experimental observations.

Keywords: fluorinated alcohols, hexafluoroisopropanol, infrared spectrum, quantum chemical calculation, anharmonicity, local modes model.
