摘要：

The theoretical parameters underlying quantitative Raman spectroscopy left bracket relative normalized differential Raman scattering (RNDRS) cross sections right bracket are discussed. A method is described left bracket based on Placzek's polarizability theory right bracket by which relative abundances of species of geological interest (e. g. , CO//2, CH//4, SO//2) in individual fluid inclusions are analyzed in practice. Whereas the precision of the analysis is determined by 'practical limitations' (which include counting statistics and instrumental reproducibility), its accuracy depends on 'practical' as well as 'theoretical limitations'. The latter are due to uncertainties in the available RNDRS cross sections.
