Infrared & Raman Users Group

IRUG is a community that encourages the sharing of high quality comparative reference spectral data.

We develop IR and Raman reference spectra for the study of works of art, architecture, and archaeological materials. Our database is peer-reviewed through a rigorous process facilitated by this website.

Anyone may search the database to view and print spectra. To access digital spectra and related information, you must join IRUG and contribute spectra. Click the button below to begin registration.
