WebbAs a result, Raman spectroscopy requires no or little sample preparation in measurement of solids, liquids, and gases. Not only directly, but also through transparent windows such as glass and plastic. Water has very low Raman signal and therefore Raman spectroscopy can easily detect compounds that dissolved in water without strong interference. WebbRaman Shift Calculator. Raman spectroscopy is a form of vibrational spectroscopy technique where vibrational, rotational frequencies and low-frequency modes of a system caused by the inelastic scattering of light (the Raman shift) are monitored. These vibrational frequencies are used as chemical fingerprints for the identification of …
