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 .
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.
Raman
Spectra. Our data are 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 and Caltech. This database has chemical analyses,
X-ray
diffraction parameters, Raman spectra, and, infrared spectra and,
ultimately, other types of
data in a convenient,
single database.
Mössbauer
Spectra.
A
very small sampling of spectra on this site. Contact us if you have
Mössbauer spectra of minerals to contribute or links to
collections of mineral data.
Compare
the emission (from ASU), reflection (from JPL) and transmission spectra
of quartz.
You are invited to contribute
data to our site
You can e-mail data to me.
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.
