Raman spectroscopy; Raman spectrometry
Technical term used in physics, chemistry, and materials science for measuring Raman scattering to analyze molecular vibrations.
This sample was analyzed by Raman spectroscopy.
Raman effect, the physical phenomenon underlying Raman spectroscopy.
Spectroscopy in general; ラマン分光測定 specifically refers to the measurement process using Raman scattering.
From ラマン (Raman, after C. V. Raman) + 分光 (spectroscopy) + 測定 (measurement).
