Abstract

Six new electronic transitions of NiCl, recorded by high-resolution Fourier transform spectroscopy, have been studied. The identification of the states involved in these transitions has been made possible by dispersing laser-induced fluorescence at low resolution. Comparison of the results obtained using these two experimental techniques allowed us to locate the [1.6]A(2)Delta (3/2) (nu = 0) spin-orbit component at 1646 cm(-1) above the X(2)Pi (3/2) groundstate. Two other low-lying states have also been identified: the first one, located 382 cm(-1) above the ground state is a good candidate to be the X(2)Pi (1/2) component of the X(2)Pi (i) state. A second state at 1385 cm(-1) in the energy level diagram could be a component of a quartet state of NiCl. In addition we have identified a Omega = 3/2 state 21608 cm(-1) above the X(2)Pi (3/2) ground state. The [22.3](2)Delta (3/2) spin-orbit component associated with already known [21.9](2)Delta (5/2) sublevel has also been identified. (C) 2001 Elsevier Science.
