Raman spectroscopy is an analytical technique where scattered light is used to measure the vibrational energy modes of a sample. It is named after the Indian physicist C. V. Raman who, together with his research partner K. S. Krishnan, was the first to observe Raman scattering in 1928.1 Raman spectroscopy can provide both chemical and structural information, as well as the identification of substances through their characteristic Raman ‘fingerprint’.

Raman spektroskopisi
Genel bilgiler
Moleküler titreşimleri ölçmek için kullanılan bir spektroskopi yöntemidir. Bu yöntem, moleküllerin "yapısal parmakizlerini" tanımlamak için çokça kimya laboratuvarlarında kullanılır. Adını Hintli fizikçi Chandrasekhara Venkata Raman'dan alır.
