  2. UH Raman Group What is Raman Spectroscopy ? Why need Raman Spectra ? • Raman spectra Beam splitter Laser Vibrational modes of molecules Sample Notch Filter Depends on atomic mass, bond lengths, bond strength, configuration, etc… Spectrograph CCD Unique spectrum for each molecule * Raman Fingerprints: Chemical detection with very high confidence level

  3. UH Raman Group Typical Raman spectra (in 1 second) 1085 282 Calcite CaCO3 Intensity (a.u.) Notch filter 801 Cyclohexane C6H12 1444 Raman Shift (cm-1) Laser at 0 cm-1 • Sharp well defined peaks • Unique spectrum for each chemical • Can also tell polymorphs

  4. UH Raman Group Remote Raman Spectra of various minerals
