THE PERMANENT ELECTRIC DIPOLE MOMENTS OF THE $X^{3} \Delta, E^{3}\Pi, A^{3}\Phi$ AND $B^{3}\Pi$ STATES OF TITANIUM MONOXIDE, TiO

Abstract

Author Institution: Department of Chemistry and Biochemistry, Arizona State University; Chemistry Department, Brookhaven National LaboratoryThe optical Stark spectrum of the origin bands of the $E^{3}\Pi_{0} - X^{3}\Delta_{1}, A^{3}\Phi_{2} - X^{3}\Delta_{1}$, and $B^{3}\Pi_{0} - X^{3}\Delta_{1}$ band systems of titanium monoxide, TiO, were analyzed to produce permanent electric dipole moments of $3.34(1)D, 3.2(4)D, 4.89(5)D$ and $4.9(2)D$ for the $X^{3}\Delta_{1}, E^{3}\Pi_{0}, A^{3}\Phi_{2}$ and $B^{3}\Pi_{0}$ states, respectively. The observations are compared with a simple molecular orbital description for the low-lying states and electronic structure calculations
