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.Join IRUG

IRUG pays tribute to the life of Andrew Lins, former chair of the Philadelphia Museum of Art, Conservation Department, who passed away on Christmas Day, 2019. Andrew was a highly accomplished conservator, scientist and renowned expert on metals and corrosion. His rich life and many accomplishments have been well-recognized. Less known is the importance of Andrew's early leadership that made possible IRUG's incorporation in the early 1990s. He firmly believed in the Group's mission of collaboration in the pursuit of accessible, high-quality reference data among institutions. Andrew was an unwavering advocate throughout IRUG's existence. His continued support greatly helped to propel IRUG on an international level. With fond memories, we always will be grateful for his guidance and friendship.
