拉曼光谱范围

下表列出了几个功能组的常用拉曼光谱范围。希望了解的更为全面,我们向您推荐George Socrates (John Wiley & Sons, 2004)所著Infrared and Raman Characterstic Group Frequencies.

我们将不断更新此表.

Frequency Range (in cm-1) Band Assignment Remarks
2700-3100 C-H alkyl free vibrations Medium intensity in Raman
2230 C≡N stretch very strong band in Raman, found in most cyanide based compounds
2190-2300
C≡C (triple bond stretch)

very strong in Raman
2100-2140 C≡C (triple bond stretch) very strong in Raman
1650-1750 C=O stretch Ketones appear on the lower wavelength side, aldehydes appear on the higher side
1600-1675 C=C stretch
Very strong in Raman
1580-1620
C=C stretch

Very strong in Raman
990-1010 Aromatic ring breathing
Appears at 992 cm-1 for benzene, around 1004 cm-1 for toluene.
650-850 C-Cl stretch Strong in Raman
