Dipole oscillator strength distributions and properties for methanol, ethanol, and n-propanol

Abstract

Dipole oscillator strength distributions (DOSDs) have been constructed for ground state methanol, ethanol, and n-propanol and used to evaluate integrated ("band") oscillator strengths and the dipole oscillator strength sums Sk and Lk (for a variety of k values) for these molecules. Each DOSD is constructed by using available experimental and theoretical photoabsorption cross sections and by constraining the resulting dipole oscillator strength data to satisfy the Thomas–Reiche–Kuhn sum rule and molar refractivity constraints. The discussion includes an analysis of the reliability of the results.
