Abstract
WE have recently investigated the fundamental stretching vibration of liquid water in the infra-red region 4,000–2,000 cm−1 using the thin cell technique developed by Thompson1. The spectra, recorded under high-resolution conditions on a Perkin–Elmer 125 spectrometer, are shown in Fig. 1. It is apparent that the absorption in the 3,450 cm−1 region is complex and composed of three bands with frequencies of ∼3,625 cm−1, 3,410 cm−1 and 3,250 cm−1. The band profile is almost identical to that observed in the Raman effect (see, for example, Schultz and Hornig2).
