Raman Spectroscopy – From Spectra to Knowledge
Gene Hall, Michael Boruta
Abstract
As Raman spectroscopy continues to grow the need for tools to assist in the identification and interpretation of Raman spectra grows with it. The task of interpreting unknown spectra has always relied on experience, text books, reference spectra, software tools to assist with the interpretation and any prior knowledge of the chemistry of the sample. Although traditional databases have always been good at identifying exact matches, their ability to assist with interpretation of unknowns has been limited. Because of the limited size of reference collections for Raman spectroscopy, the possibly of finding exact matches is reduced and there is a greater reliance on interpretation skills. This limitation of using reference spectra for interpretation has been primarily due to a lack of spectra structure correlations associated with the reference spectra. Without this knowledge of spectra structure correlations, interpretation of an unknown spectrum from a set of reference spectra is very difficult. Recently work at Rutgers University has been undertaken to compile a database of Raman spectra along with accompanying structures and band assignments. This unique database should prove to be a valuable tool to assist spectroscopists in the interpretation of Raman spectra. The progress on this work will be reported.
