Scientific paper

Recently the New Brunswick group reported on the field-free detection and analysis of the A3Φ4-X3Φ4 band system of IrF. Here we report on the analysis Q(4)(15922 cm-1) branch feature of the (1,0) band of the 191IrF isotopologue of that system recorded at field strengths of up to 3000 V/cm. The spectra are surprisingly complex at the achieved resolution of 40 MHz due to the presence of both the 191Ir(I=3/2) and 19F(I=1/2) magnetic hyperfine splitting. The determined permanent electric dipole moment, μel, for the X3Φ4 state is compared with that recently determined for the X3Φ4 state of isovalent CoF. The trend in μel amongst the ground states of IrF, IrC and IrN will be discussed. Finally, a simple molecular orbital correlation diagram will be used to rationalize the change in μel upon excitation from the X3Φ4 to A3Φ4 state.
