Our reflectance data
from oriented
crystals in the 1800 - 400 cm-1
range.
Our ATR (Attenuated
Total Reflectance) data of hundreds of mineral
powders
on a diamond plate in the 4000 - 450 cm-1 range
are now incorporated in the RRUFF project.
An extensive
collection of reflectance
spectra of minerals is available
from the USGS
Spectroscopy Lab .
The CRISM Spectral Library
at Washington University, St. Louis, that has large collection of
reflectance data on a variety of mineral and related materials.
A limited collection
of infrared reflectance spectra
of minerals is available from the the
Chemical and Spectroscopy Laboratory at
the Astrophysics Institute and University Observatory, Jena, Germany.
Spectra of samples characterized at Caltech, often in conjunction with
the Natural History Museum, Los Angeles County, but which have not been
processed for the Arizona RRUF site are in a separate RAMAN DATABASE.
Much of our data is now part of the RRUFF
project, a large
composite database that combines the American
Mineralogist Crystal Structure Database
with thousands of Raman spectra obtained at Arizona State
University. This database has chemical analyses,
X-ray
diffraction parameters, Raman spectra, and, Caltech infrared spectra in a convenient,
single database.

Mars Mineral Spectroscopy Database
an extensive database of spectra and ASCII data
maintained by M. Darby Dyar at Mount Holyoke
College, South Hadley, Massachusetts, USA.
Data presented on this site
have been obtained, in part, through the support from research grants
of the National
Science Foundation (USA), the
White Rose Foundation, and through the generosity of individuals
throughout the world who are willing to share their data in a community
resource.
