Abstract
Three near infrared electronic transitions of NiCl have been reanalyzed. Hougen's recent (2011) theoretical investigation of low-lying states of metal halides with a $d^{9}$ electronic configuration indicated that the signs of the experimental spin-rotation and lambda-doubling signs for the low-lying $\Omega$=1/2 states of NiCl were not correct. This problem is corrected by assuming an excited state with $^{2}\Sigma^{-}$ symmetry instead of $^{2}\Sigma^{+}$ symmetry. Line positions for the $[12.3]^{2}\Sigma^{-}$ - $X^{2}\Pi_{3/2}$, $[12.3]^{2}\Sigma^{-}$ - $X^{2}\Pi_{1/2}$, and $[12.3]^{2}\Sigma^{-}$ - $B^{2}\Sigma^{+}$ electronic transitions have been refitted, and the new spin-rotation and lambda-doubling signs agree with the Hougen theory. The results of the analysis will be presented.
