Differences in two-photon and one-photon absorption profiles induced by vibronic coupling: the case of dioxaborine
1State Key Laboratory of Crystal Materials, Shandong University, 250100 Jinan, Shandong, China.
Abstract:
A theoretical study of a dioxaborine heterocyclic compound in solution provides a case study for an analysis of the effects induced by the so-called Herzberg-Teller (HT) vibronic coupling on the one-(OPA) and two-photon absorption (TPA) spectra. For TPA, the HT vibronic coupling induces differences in the shapes of the absorption band. The study highlights the importance of vibronic coupling as a potentially important mechanism in absorption spectroscopy, able to explain differences in the OPA/TPA spectra.
