Emission bands of the TiH radical in the region 18 000-20 000 cm(-1) have been recorded both with grating spectrograph and Fourier transform techniques. The rotational structure of the 530 nm band, which is the strongest one of the three observed bands, has been analyzed and molecular parameters have been derived for the electronic states involved. The electronic assignment of this band is confirmed as (4) Gamma-->X(4) Phi, with a heavily perturbed upper state. The principal parameters (cm(-1)) of the analyzed states are X(4) Phi (nu=0) : A=33.083(29), B=5.362 06(19), and gamma=0.1823(27). (4) Gamma (nu=0) : T=18 878.10(47), A=41.54(10), B=5.7408(22), gamma= -4.33(12), and lambda=0.77(14). The derived first order spin-orbit parameter values of X(4) Phi, and (4) Gamma are shown to be consistent with the electronic configurations delta pi sigma and delta pi pi’, respectively. The local perturbations in the (4) Gamma state are discussed and arguments are given to suggest that the dominating perturber is of (4) Phi symmetry.
