The IR spectrum of liquid hydrogen fluoride

摘要

The IR spectrum of liquid hydrogen fluoride has been obtained in the frequency region 4000-1100 cm~(-1). The spectra of its first and second derivatives have been mathematically computed. The positions of the maxima of the observed bands are determined. The v(HF) contour of the valence vibration band displays several separate components, which are evidence of the formation in liquid HF of a set of various polymeric clusters similar to the clusters formed in the vapor phase.
