Abstract

The near-normal incidence spectral reflectance of deuterium oxide at 27 °C has been measured in the spectral range 6800–350 cm⁻¹. Kramers-Kronig phase shift analysis has been applied to measured reflectance to obtain values of the real and imaginary parts of the complex index of refraction $\hat{N}$(ν) = n(ν) + ik(ν). The results are compared in detail with the corresponding optical constants of ordinary water at 27 °C. In general, the D₂O absorption bands are narrower and less intense than the corresponding bands in ordinary water.
