The electronic absorption bands of many molecules in solution have half widths at half-height of about 5000 cm−1.

(a) Estimate the integrated absorption coefficient of a band for which εmax ≈ 1.9 ✕ 103 dm3 mol−1 cm−1

(b) Estimate the integrated absorption coefficient of a band for which εmax ≈ 8.6 ✕ 103 dm3 mol−1 cm−1

please answer in dm3 mol−1 cm−1
