Question:

The absorption associated with a certain transition begins at 199 nm, peaks sharply at 220 nm, and ends at 275 nm. The maximum value of the molar absorption coefficient is 2.25 x 104 dm3 mol-1 cm-1. Estimate the integrated absorption coefficient of the transition assuming an inverted parabolic line shape (Fig. 14.49; use eqn 13.5).
