The Fourier transform emission spectrum of the A3Π0-X1Σ+ band system of InCl

For the first time, the emission spectrum of A(3)Pi (0)-X(1)Sigma (+) band system of InCl molecule has been recorded on BOMEM DA8 Fourier transform spectrometer at an apodized resolution of 0.025 cm(-1). The rotational structure of 1-0, 2-1, 0-0, 0-1, 1-2, 0-2, and 1-3 bands belonging to the A(3)Pi (0)-X(1)Sigma (+) transition of (InCl)-Cl-35 has been analyzed and accurate equilibrium rotational constants of the A(3)Pi (0) state obtained. It has also been possible to unambiguously assign rotational lines of 1-0, 0-0, and 0-1 bands belonging to (InCl)-Cl-37 isotopomer. No perturbations have been observed contrary to what has been reported by some of the earlier workers. (C) 2001 Academic Press.
