UV Visible Spectroscopy
EMR = Kind of energy with wave character that can be characterized by using wavelength, frequency, velocity and amplitude
-
Electronic Transition
-
n → σ * = R-OH, R-OR, R-NH2, R- SH
-
n →π * = R-COOH, R-COOR, RHC= O, R2C=O
Chromophore= Any isolated covalently bonded groups that absorbs light and imparts colour.
Eg = C=C,C=O, NO
Auxochrome= Any group which does not itself acts as a chromophore but when attached on chromophore it shifts the absorption band towards the red shift. Eg = OH, NH2, CHO
