The first spectroscopic investigation of the (A) over tilde (1)A ''-(X) over tilde (1)A' transition of HSiNC has been reported. The 0(0)(0) band of the (A) over tilde (1)A ''-(X) over tilde (1)A' transition has been rotational resolved using laser-induced fluorescence spectroscopy, and ground- and excited-state rotational and centrifugal distortion constants were evaluated. Ten additional vibrational bands belonging to HSiNC have also been observed in the laser-induced fluorescence spectrum and have been assigned based on predicted anharmonic vibrational frequencies. Because of the large change in geometry upon excitation, a number of axis-rotation peaks have been observed in the 0(0)(0) band, and the axis-rotation angle (theta(T)) has been estimated to be 1.0 +/- 0.2 degrees. Dispersed fluorescence spectroscopy has also been carried out, and a number of overtones of the nu(3) fundamental (Si-H wagging mode) have been observed in the ground state, and its anharmonic parameter (x(e)) was evaluated.
