AbstractA brief review is given of how a constrained dipole oscillator strength distribution (DOSD) is constructed from experimental and possibly theoretical photoabsorption cross-sections with constraints provided by molar refractivity data and the Kuhn–Reiche–Thomas sum rule. Some recent refinements including the imposition of the correct high-energy behavior on the DOSD for homoatomic molecules are discussed and extended to the general molecular case. A sample application to pyridine is given.

Newly available and highly accurate oscillator strength data, extending over the continuous energy range from the first excitation threshold to 200 eV, are used together with mixture rule estimates and other photoabsorption data to construct a refined dipole oscillator strength distribution to infinite photon energy using Thomas–Reiche–Kuhn sum rule and molar refractivity constraints. This constrained dipole oscillator strength distribution has been used to calculate a wide range of related dipole properties (Sk, k = 2, 1, 0, −1/2, −1, −3/2, −2, −5/2, −3, −4, −5, −6, −8, −10, −12; Lk and Ik, k = 2, 1, 0, −1, −2). The theoretical analysis and associated consistency checks support the high accuracy of the newly available absolute oscillator strengths for the photoabsorption of NH3.
