The Raman Spectrum of Heavy Water Vapor

Abstract
The Raman spectrum of heavy water vapor was obtained by using water having a d2020 = 1.073, at two atmospheres pressure. A line Δv = 2666 cm—1 was found for D2O and Δv = 2718 cm—1 for HDO. The other line expected from the work of Wood on liquid heavy water in the region Δv = 3700 cm—1 was not found. The line Δv = 3650 cm—1 of H2O was resolved into a doublet Δv = 3646.1 cm—1 and Δv = 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.
