Raman spectroscopy
A spectroscopic technique used to observe vibrational, rotational, and other low-frequency modes in a system. Commonly used in chemistry and physics.
Raman spectroscopy is used to investigate the vibrational modes of molecules.
From English 'Raman spectroscopy', named after Indian physicist C. V. Raman. The Japanese term combines the katakana rendering ラマン with 分光法 (spectroscopy).
