ROTATIONAL ANALYSIS OF FOUR SINGLET SYSTEMS OF AsF

Abstract

Four violet degraded band systems in the region 2290-2910 {\AA} attributed to AsF have been observed in a microwave discharge through flowing $AsF_{3}$ vapour. The transitions have been found to involve the four singlet states a $^{1}\Delta, b^{1}\Sigma, c^{1}\Pi$ and d $^{1}\Pi$. The rotational analysis of these systems will be discussed in detail.
