Raman Spectral Interpretation

Michael Boruta, Eugene Karpushkin

Abstract

With the continued growth of Raman spectroscopy usage and applications, the need for databases and interpretation tools grows with it. As with infrared, the interpretation of Raman spectra can be a difficult task. Raman spectra interpretation is often more difficult because there are fewer resources available to the spectroscopists. Traditionally, interpretation of spectra relies on experience, text books, reference spectra and any prior knowledge of the chemistry of the sample. Software tools that can assist the spectroscopists in the verification, interpretation or classification of these spectra can be invaluable and cost-effective asset, both in terms of efficiency and accuracy. This poster will briefly look at the resources available today to the Raman spectroscopists and examine more recent progress in software assisted structure verification and spectral interpretation. We will describe the use of software combined with a knowledgebase of spectra-structure correlations to aid in the verification of suspected materials and the interpretation of unknown materials. The organization of this knowledgebase along with some limitations of the knowledgebase and several examples to explore the knowledgebase will be discussed.
