Abstract:

Raman spectroscopy is a powerful, non-destructive analytical technique for identifying minerals through their unique vibrational spectral "fingerprints." Yet, natural history collections at many universities lack the reference databases needed to fully utilize this technology. At West Texas A&M University, an institution without the resources to purchase a commercial spectral database, we are addressing this gap by developing an in-house Raman spectral reference library using the university's extensive Ward's mineral collection. As an initial step, Raman spectra are being systematically collected for all rock-forming minerals using a Horiba Raman spectrometer and verified against the RRUFF Project database.

In addition to creating a practical reference library for WTAMU, this project establishes a standardized operating procedure (SOP) for the Raman spectrometer, providing a reproducible workflow that other resource-limited institutions can adapt to develop their own spectral databases. The project also has a strong educational component by engaging undergraduate researchers in analytical instrumentation, database development, and scientific methodology while creating resources that can be incorporated into geology instruction and K–12 outreach.

Once the reference library for rock-forming minerals is completed, the workflow will be expanded to additional specimen types within the collection, including bone, feathers, and teeth. As part of the Texas Panhandle Natural History Digital Archive, this project enhances the research value of an existing but underutilized collection while creating an accessible resource for research, education, and public engagement. The resulting workflow and spectral database are intended to serve as both a practical institutional resource and a transferable model for similar regional collections.
