The probability of absorption of a photon by a molecule (at a given wavelength) can be represented as the ratio of two areas [6, 58, 59]: $$ P = \delta /X $$ (2.1) where δ is the absorption cross-section, i. e. “the area impermeable for a photon” [6], and X is the cross-sectional area of the molecule; δ does not exceed X. δ(A2) should be converted to the molecular extinction coefficient E(A2) The conversion from δ to E requires to multiply E by 2.3, i.e., δ=2.3E. The value 2.3 arises… CONTINUE READING
