Phys. Lett. {\bf 159}, 563, The visible line frequencies used in the analysis were taken from: Melville and Coxon, 2002, J. Phys.Chem. A {\bf 106}, 8271. The frequency analysis includes electronic states from A $^1\Sigma^+$ v = 0-3 to X $^1\Sigma^+$ v = 0-3. The ground state and the A state were fitted using equilibrium parameters. The A $^1\Sigma^+$ v =3 was fitted with perturbation from two dark states included. The dipole moment was estimated from similar species.
