To Do: Migrate


In 2003, the Infrared and Raman Users Group received NCPTT support to develop and implement an online collaborative database and bibliography of high quality infrared reference spectra.  The Infrared and Raman Users Group is a “collaboration to encourage the exchange of information, develop IR and Raman spectral standards, and distribute comparative spectral data for the study of works of art, architecture, and archeological materials.”  (

According to the website, the IRUG database is “an ongoing, collaborative compilation of peer-reviewed spectra of artists’ and related materials for the study of the world’s cultural heritage.  Currently, the database contains over 1250 spectra of oils, waxes, natural and synthetic resins, dyes, pigments, proteins, gums, and minerals.  Scientists and other professionals from the art conservation, historic preservation, and academic communities have generously contributed their spectra to the Database.” (
