  9. Forbidden transition: P = 0.01; e < 103 Allowed transition: P = 0.1 to 1 Strong absorption: e = 104 to 105 L/ (mol*cm) Weak absorption: e =103 L/ (mol*cm) The Magnitude of Molar absorptivity is0 to around 105 e = 8.7 x 1019 P A P: transition probability (0 to 1) A: cross sectional target area in square centimeters (for organic molecules, this number is around 10-15 cm2).
