The Zeeman effect on the F-1/2←3/2 hyperfine component of the R(0) line in the (0,0) band of the A1Π-X1Σ+ transition of iridium mononitride, IrN, was investigated using a supersonic molecular beam optical spectrometer. The magnetic gJ-factor for IrN in the A1Π state was determined to be 0.96±0.05. The general applicability of Zeeman measurements is described and the gJ-factor which is determined is related to plausible molecular orbital descriptions for IrN in the A1Π state.
