This bundle presents room temperature  (18-19 degrees Celsius) diamond anvil cell thin film absorption        spectra of a large suite of olivines evenly spaced across Mg and Fe    compositions at infrared wavelengths.  In each file, the left column   is the frequency in wave numbers (units: cm**-1).  The right column is the chemical absorbance (common logarithm based).", "identifier": "urn:nasa:pds:gbo.olivines.pitman.lab-spectra", "issued": "2021-05-21", "keyword": ["meteoritic-fo81", "msng-fo0", "natural-fayalite-fo0", "natural-fo14", "natural-fo31", "natural-fo41", "natural-fo45", "natural-fo54", "natural-fo63", "natural-fo68", "natural-fo9", "natural-fo91", "natural-fo93", "none", "synthetic-fo100", "synthetic-fo50", "synthetic-fo67", "synthetic-fo75", "synthetic-fo80"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewBundle.jsp?identifier=urn%3Anasa%3Apds%3Agbo.olivines.pitman.lab-spectra&version=1.0", "license": "http://www.usa.gov/publicdomain/label/1.0/", "modified": "2025-07-17", "programCode": ["026:005"], "publisher": {"@type": "org:Organization", "name": "National Aeronautics and Space Administration"}, "references": ["https://pds.nasa.gov"], "theme": ["Earth Science"], "title": "OLIVINE LABORATORY INFRARED ABSORBANCE SPECTRA"}
