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
The IRUG14 Conference, originally scheduled for May 27-29, 2020, at The Cultural Heritage Agency of the Netherlands, Amersfoort (RCE), has been rescheduled for May 19-21, 2021.
The coronavirus has disrupted travel for many people, and there is uncertainty among the conference participants regarding attendance. Therefore, after careful consideration, the IRUG Board of Directors and RCE have decided to postpone this year’s conference to May 19-21, 2021. By rescheduling, we will ensure regular attendance and a successful event.
We understand that the postponement will be both a disappointment and a relief to many, and we thank you for your understanding. If you are a speaker, attendee/participant, or sponsor, you will receive an email notification. If you have paid the IRUG14 conference registration fee, it will be refunded.
Please direct all inquiries and correspondence to IRUG14@cultureelerfgoed.nl.
We deeply appreciate your participation in IRUG and wish everyone well.
