OS100: A Benchmark Set of 100 Digitized UV-Visible Spectra and Derived Experimental Oscillator Strengths.

Excited-state quantum chemical calculations usually report excitation energies and oscillator strengths, , for each electronic transition. On the other hand, UV-visible spectrophotometric experiments measure energy-dependent molar extinction/attenuation coefficients, ε(), that give absorption band line shapes when plotted. ε() and are related, but this relation is complicated by broadening and solvation effects.
