Abstract
Since the intermolecular structure of water is dependent upon temperature, changes in the infrared spectrum dependent upon temperature are expected to occur. Hale et $al.^{1}$ have obtained values for the Infrared optical constants $\hat{N} = n + ik$ of water at 5, 27, and $70^\circ$ C and have observed shifts of major band positions and shapes. These studies have been extended to include measurements of the near-normal incidence Infrared reflectance of water at 1, 16, 39, and $50^\circ C$, Values for the optical constants of water at those temperatures have been calculated using Kramers-Kronig analysis. The results obtained indicating changes in water band positions and shapes will be presented and compared with previous results.
