RRUFF PROJECT

Raman Spectra on the Mineral Spectroscopy Server have been placed with the RRUFF Project, a project under the direction of Professor Robert Downs at the University of Arizona, in collaboration with Caltech Mineralogy. Numerous Caltech infrared ATR spectra of minerals are also being placed on this site. The RRUFF Project contains the largest collection of quality Raman spectra of minerals available from any source. It also has one of the largest (but still incomplete) collections of mineral ATR data.
