Two-photon Absorption Spectra of a Near-IR Polymethine Molecule with a Broken Ground-State Symmetry

Not Accessible

Your library or personal account may give you access

Abstract

NIR polymethines are studied in two solvents of dissimilar polarity to investigate predictions of 2PA enhancements from ground-state symmetry-breaking (SB). However, electron-vibrational coupling appears to predominate SB.
