The open question of the absolute neutrino mass scale will be addressed by the Karlsruhe Tritium Neutrino (KATRIN) experiment, currently under construction. This thesis reports major contributions to developing and implementing new laser-spectroscopic precision tools to continuously monitor the isotope content of the windowless gaseous tritium source of KATRIN. The method of choice, Raman spectroscopy, is ideally suited for in-situ monitoring of all six hydrogen isotopologues. In a series of beautiful experiments the author obtained two independent novel calibration methods, first based on a comparison of experimental Raman depolarization ratios with corresponding quantum-chemical calculations, and second on a gas sampling technique. Both methods yield consistent cross-calibration results and, as well as yielding improvements in precision, will be of major importance in reducing systematic effects in long-term neutrino mass measurements. The methods developed in this thesis also have great potential to further broaden the applications of Raman spectroscopy to study extended sources such as in atmospheric physics. . 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aElementary particles (Physics) 606 $aQuantum field theory 606 $aAtomic structure   606 $aMolecular structure  606 $aSpectroscopy 606 $aMicroscopy 606 $aElementary Particles, Quantum Field Theory$3https://scigraph.springernature.com/ontologies/product-market-codes/P23029 606 $aAtomic/Molecular Structure and Spectra$3https://scigraph.springernature.com/ontologies/product-market-codes/P24017 606 $aSpectroscopy and Microscopy$3https://scigraph.springernature.com/ontologies/product-market-codes/P31090 615 0$aElementary particles (Physics). 615 0$aQuantum field theory. 615 0$aAtomic structure  . 615 0$aMolecular structure . 615 0$aSpectroscopy. 615 0$aMicroscopy. 615 14$aElementary Particles, Quantum Field Theory. 615 24$aAtomic/Molecular Structure and Spectra. 615 24$aSpectroscopy and Microscopy. 676 $a535.846 700 $aSchlösser$b Magnus$4aut$4http://id.loc.gov/vocabulary/relators/aut$0791826 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910300396803321 996 $aAccurate Calibration of Raman Systems$91770465 997 $aUNINA
