| 释义 | > as lemmasresonance Raman resonance Raman n. Physics attributive designating a spectroscopic technique in which a Raman spectrum is excited by light having a frequency equal to that of an allowed electronic transition of the scattering molecules, leading to enhanced vibrations of parts of the molecule involved in the transition; relating to or involving this technique; (also, not attributive) resonance Raman spectroscopy.

Ya. Karpov tr. P. P. Shorygin & L. L. Krushinskii in Soviet Physics-Doklady 5 793 The possibility of observing resonance Raman spectra is limited to a considerable degree by the loss of light due to absorption. 1983 G. Britton Biochem. Nat. Pigments i. 18 In work with pigments the technique used is resonance Raman spectroscopy. 1997 New Scientist 19 Apr. 70/2 (advt.) Applications are invited..to work on various aspects of the new very sensitive technique of surface enhanced resonance Raman scattering. 2005 J. W. Robinson et al. Undergraduate Instrumental Anal. (ed. 6) iv. 301 This makes resonance Raman a very selective probe for specific chromophores. < as lemmas |
