The Raman spectra of a large number of natural feldspar-group minerals were obtained to determine what compositional and structural information can be inferred solely from their Raman spectra. The feldspar minerals selected cover a wide range of Na,

We have extensively modified and successfully used a laser Raman spectrometer (DORISS, deep-ocean Raman in situ spectrometer) for geochemical studies in the deep ocean. The initial instrument, from Kaiser Optical, was separated into three components:
