Abstract

The electronic specturm of diatomic PbCl molecule has been excited in RF discharge source and (0,4 and (0,5) bands at 4846.0 \AA\,\, and 4916.4 \AA, respectively, have been photographed at a resolution of 2\times 10^{5} in PGS-2 (Carl-Zeiss) using kodak 103-0 plates and a fine slit of 30 \mum. Rotational analysis of the bands has been performed and molecular constants including \alpha_{e} and \beta_{e} are reported. A detailed investigation leads to the proposition that the bands arise due to the electronic transition (1/2)\rightarrow (1/2) equivalent of A^{2}\sum \rightarrow X^{2}\Pi_{1_{/2}}, both the states being in Hund's case (c).
