N2 - Laser induced fluorescence spectra of the (1, 0) band of the [17.9]4 – X3Φ4 transition of iridium monochloride, Ir35Cl, have been obtained at near natural linewidth resolution using supersonic molecular beam techniques. The spectra show clearly resolved hyperfine structure which has significant contributions from the magnetic and nuclear electric quadrupole hyperfine terms in 193Ir and 191Ir, both with I = 3/2, but no resolved contribution from Cl hyperfine structure (I = 3/2). The spectra of both 193IrCl and 191IrCl isotopologues have been assigned and analyzed. The hyperfine structure, which was interpreted with the aid of atomic hyperfine parameters, showed that the configurational composition of the ground state of IrCl is similar to that determined previously for the ground state of the isovalent molecule IrF.
