UV SPECTROSCOPY II

Among organic compounds only those which are unsaturated & particularly those which are conjugated will absorb radiation (UV) in this way.
Beer-Lambert Law
(Beer’s Law)
e molar absorption
   coefficient
      A = e c l
A = absorbance
c = conc. (M)
l = path length (cm)
UV Spectroscopy = “conjugation detector +C=O”
