The near infrared electronic transition of NiCl occurring in the region of 11,900~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. This transition was observed previously at low resolution and originally labeled as System I. At this time we believe it does not connect to the ground state. A high resolution analysis of this transition is in progress and results of the fit will be presented.
