The Raman Spectrum of Heavy Water Vapor

The Raman spectrum of heavy water vapor was obtained by using water having a d(20)(20) = 1.073, at two atmospheres pressure. A line Delta nu = 2666 cm(- 1) was found for D2O and Delta nu = 2718 cm(-1) for HDO. The other line expected from the work of Wood on liquid heavy water in the region Delta nu = 3700 cm(-1) was not found. The line Delta nu = 3650 cm(- 1) of H2O was resolved into a doublet Delta nu = 3646.1 cm(-1) and Delta nu = 3653.9 cm(- 1). An attempt has been made to explain the Raman spectrum of H2O empirically by using the data of Mecke on the infrared absorption spectrum of H2O.
