WebbFebruary 1928: Raman scattering discovered. On a boat trip back from England in 1921, Indian physicist C.V. Raman, considering the question of why the sea is blue, got started on a line of research that would lead to the discovery in February 1928 of a new scattering effect, now known as the Raman effect, which is important in physics and ... WebbRaman spectroscopy could no longer compete with infrared until another development in physics — the laser — revived Raman spectroscopy in a new form beginning in the 1960s. Back to top Although Raman's original experiments were done by visual observation, precise measurements were made with this quartz spectrograph and first made public …
