“…While there are now quite a number of spectroscopic studies of rhodium-containing diatomic molecules (RhX, X = H, C, N, O, F, S, Cl, P) [8][9][10][11][12][13][14][15], there have been very few spectroscopic studies of diatomic molecules containing iridium. Only five species, IrO [16], IrC [17], IrN [18], IrF [19], and IrB [20] have been reported to date.…”
