The permanent electric dipole moments of the X 3Δ,E 3Π,A 3Φ and B 3Π states of titanium monoxide, TiO

The optical Stark spectrum of the origin bands of the E 3Π0–X 3Δ1,A 3Φ2–X 3Δ1, and B 3Π0–X 3Δ1 electronic transitions of titanium monoxide, TiO, were analyzed to produce permanent electric dipole moments of 3.34(1), 3.2(4), 4.89(5) and 4.9(2) D for the X 3Δ1,E 3Π0,A 3Φ2 and B 3Π0 states, respectively. The observations are compared with a simple molecular orbital description for the low-lying states and electronic structure calculations.
