![Analysis of hyperfine structure in the 0–0 band of the [17.6]2.5–X2.5 transition of iridium monoxide, IrO](http://166.78.47.98/steimle/wp-content/uploads/2014/05/1-s2.0-S0022285213001549-fx1.jpg)
Laser induced fluorescence spectra of the [17.6]2.5–X2.5 0–0 band of iridium monoxide, IrO, have been obtained at high resolution (<40 MHz). The hyperfine structure due to 193Ir (I = 3/2) and 191Ir (I = 3/2) is well resolved enabling determination of magnetic (h5/2) and nuclear electric quadrupole (eQq0) hyperfine parameters for the [17.6]2.5 (v = 0) and X2.5 (v = 0) states. The dominant configuration of the ground state is determined by...
The J = 1 ← J = 0 and J = 2 ← J = 1 rotational transitions of ruthenium monocarbide, RuC, have been recorded using the separated field pump/probe microwave optical double resonance technique and analyzed to determine the fine and hyperfine parameters for the X 1Σ+ state. The101Ru(I = 5/2) electric quadrupole parameter, eq 0 Q, and nuclear spin-rotation interactionparameter, CeffI , were determined to be 433.19(8) MHz and −0.049(6) MHz,...
