Abstract

The A(2)Pi-X(2)Z(+) emission band system of the MgCl molecule has been studied by means of high-resolution Fourier transform spectroscopy. Excited M-Cl molecules were produced by two different techniques: (i) at Orsay, they were created by mixing Mg vapor with a flow of He/Cl-2 and excited in a "heated" Schuller-type discharge tube, and (ii) at Waterloo, they were generated by using a copper hollow cathode lamp loaded with MgCl2 powder. Rovibronic analysis of the (0, 0) and (0, 1) bands was performed. Molecular constants were derived in a weighted nonlinear least squares fit, including both the new line positions and the previously published microwave frequencies (C) 2002 Elsevier Science (USA).
