Abstract

The pure rotational and vibration-rotational Stokes Raman spectra of flowing gaseous mixtures of the hydrogen isotopomers H2, HD, and D2 were measured in order to test the performance of the proposed tritium purity monitoring system designed for the Karlsruhe Tritium Neutrino (KATRIN) mass experimen...
