Additive Covalent Radii for Single-, Double-, and Triple-Bonded Molecules and Tetrahedrally Bonded Crystals: A Summary

“…70 It turned out that this experiment had missed rotational levels and the corrected experimental R 0 is 200.2(20) pm. 71 For the valence isoelectronic IrP(X 1 Σ g ), the Σr 3 and experimental R 0 72 are 201 and 199 pm, respectively.…”

Rotational and hyperfine structure in the [17.6]2.5–X2.5 and [23.3]2.5–X2.5 transitions of iridium monoxide, IrO

“…The broadening of the low J lines and the doubling of the higher J lines are both indications of hyperfine structure. The constant doubling of the lines at higher J was also observed in IrP [7] and IrF [10] and was shown to be caused by the quadrupole hyperfine structure of the Ir atom.…”

“…Iridium monoxide was produced in the same University of New Brunswick laser ablation/molecular beam source used to investigate IrP [7], IrF [9] and IrH/D [11]. An iridium rod was ablated with approximately 7 mJ of 355 nm radiation using the third harmonic of a Lumonics HY-400 Nd:YAG laser.…”

“…Since these complexes contain active iridium-oxygen moieties it is important to better understand the bonding in the diatomic systems. To date, seven diatomic iridium containing molecules have been studied experimentally: IrO [1][2][3], IrC [4,5], IrN [5], IrP [6,7], IrB [8], IrF [9,10], and IrH/D [11].…”
