Do- X050189 - RRUFF Database: Raman, X-ray, Infrared, and Chemistry

Important Update News

rruff.info is being updated to improve its interface and content. The beta version of the update is accessible to the public at www.rruff.net. New data is only being added to the beta site. Please note that it is in development, and some components are not functional. Once released, the address will revert to RRUFF.info.

We are grateful to NASA for the funding of this effort.
