The near infrared electronic transition of NiCl occurring in the region of 12,259~cm^-1 ~has been recorded by intracavity laser absorption spectroscopy. The NiCl molecules were produced in a nickel hollow cathode operating with an applied potential of 350 to 750 V, using 0.5 to 2.2 torr argon or helium, and a trace amount of carbon tetrachloride. At this time we believe it does connect to the X ~² _3/2 state. A high resolution analysis of this transition is in progress and results of the fit will be presented.
