Abstract

We have compared the near-normal-incidence spectral reflectance of water at 1, 16, 39, and 50 °C with the corresponding spectral reflectance of water at 27°C, at which temperature the optical constants n(ν) and k(ν) have been previously determined. By applying Kramers-Kronig analyses to the resulting values of spectral reflectance we have obtained the optical constants of water at each of the above temperatures. We present the results in graphical form for the spectral region 400–5000 cm−1 and in tabular form in the vicinity of major absorption and dispersion features. The bearing of our results on the intermolecular structure of water is discussed.
