Analysis of hyperfine structure in the 0–0 band of the [17.6]2.5–X2.5 transition of iridium monoxide, IrO

Posted on May 30, 2014

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...

Optical Zeeman spectroscopy of the (0,0) B 4Γ – X 4Φ band systems of titanium monohydride, TiH, and titanium monodeuteride, TiD

Posted on May 28, 2014

The Zeeman effect in the (0,0) bands of the B 4Γ5/2 – X 4Φ3/2 system of titanium monohydride, TiH, and titanium monodeuteride, TiD, has been recorded and analyzed. Magnetic tuning of the spectral features recorded at high resolution (full width at half maximum ≅ 35 MHz) and at a field strength of 4.5 kG is accurately modeled using an effective Zeeman Hamiltonian. The determined magnetic g-factors for the X 4Φ3/2 (v = 0) state deviate only...
