Abstract

The rotational analysis of some five bands (6,15), (2,14), (2,15), (8,20) and (2,17) of the A-X system of $As_{2}$ molecule was carried out to determine the various rotational constants. The values are comparable and more promising than those by MM. Jean D'Incan et al. The emission spectrum of $As_{2}$ was photographed under high dispersion both on concave grating and plane grating spectrographs using a microwave discharge as the source of excitation. The possible electron configurations of the $A ^{1}\Sigma_{g}^{+}$ and $X ^{1}\Sigma_{g}^{+}$ states of $As_{2}$ will be discussed.
