However, there is actually more than a correlation. The presence of the optical absorp-tion enables the resonance Raman phenomenon, and the resonance is quite sensitive to the excitation wave-length; that is, the important param-eter in the resonance phenomenon is
WebbHowever, applications of traditional, or normal, Raman spectroscopy have been limited by the intrinsic nature of the scattering phenomenon itself. As such, low concentration, complicated mixtures, and sample fluorescence prevent full incorporation of Raman methods into forensic analytical schemes beyond assessment of pure samples and bulk … Raman spectroscopy (named after Indian physicist C. V. Raman) is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. Raman spectroscopy is commonly used in chemistry to provide a structural fingerprint by which molecules can be identified.
