Abstract

Fourier transform emission spectra of CoCl were obtained with a tube furnace-DC discharge source in the 450-500 nm spectral region. In addition to observing two different band systems, which were assigned as [20.7](3)Phi(4)-X(3)Phi(4) and [21.3](3)Phi(4)-X(3)Phi(4) by Adam et al. [J. Mol. Spectrosc. 212 (2002) 111], we obtained data for additional sub-bands and vibrational levels. In contrast to the previous work, intense Q branches are seen in the [21.3]-X(3)Phi(4) bands which indicate that these bands are likely DeltaLambda not equal 0 transitions. The equilibrium rotational constant B-e for the ground X(3)Phi(4) state is 0.1801104(28) cm(-1), the equilibrium bond length is 2.065122(16) A and DeltaG(1/2) is 430.418(5)cm(-1). @ 2003 Elsevier Science (USA).
