Definitions and units. The UV-VIS absorption spectrum of a solution is a function of the concentration, c1, ex- pressed in mol/L, of all absorbing spe- cies present; the path length, d, of the spectrophotometer cell, expressed in cm; and the molar absorption (extinc- tion) coefficient,ei, of each species. The absorbance (optical density) A of the solution is then given by: A = d∑εici i For a resolvable absorbance peak, the band width λ is the wavelength range, expressed in nm=10¥9 m, of the peak at half the absorbance maximum.
