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 when you are ready to contribute spectra.

Date: 26-29 September 2023
Location: Tokyo National Research Institute for Cultural Properties, Tokyo, Japan
Hosted by theConservation Science Laboratory at theTokyo University of the Arts (Geidai) and theTokyo National Research Institute for Cultural Properties (Tobunken), and organized byBoris Pretzel andMasahiko Tsukada, the conference was a resounding success!Presentations took place atTobunken, and the workshop on reflectance infrared techniques was led byDr. Marcello Picollo (IFAC, Italy), with additional instruction fromDr. Suzan de Groot (RCE, The Netherlands) andProfessor Manfred Schreiner (Akbild, Austria).
Dr. James A. de Haseth, Emeritus Professor of Chemistry, University of Georgia, US, delivered thekeynote address on the theory and challenges ofreflectance mode infrared spectroscopies. We are grateful for the generous support provided byThermo Fisher Scientific, our Silver-level sponsor, as well as our Bronze-level sponsors:Bruker,Nanophoton,PhotoThermal/Nihon Thermal Consulting,Shimadzu, andST Japan.
