The rotational spectrum of the NiI radical in the XΔ5∕22 and AΠ3∕22 states

The millimeter- and submillimeter-wave spectra of the NiI radical in the XΔ5∕22 and AΠ3∕22 states were observed by a source-modulated microwave spectrometer. The NiI radical was generated by a dc glow discharge in the mixture of CH3I vapor and Ar gas through the sputtering reaction with a Ni cathode...

Description
Summary:The millimeter- and submillimeter-wave spectra of the NiI radical in the XΔ5∕22 and AΠ3∕22 states were observed by a source-modulated microwave spectrometer. The NiI radical was generated by a dc glow discharge in the mixture of CH3I vapor and Ar gas through the sputtering reaction with a Ni cathode. Observed transition frequencies for each electronic state were independently analyzed using a polynomial energy expression based on Hund’s case (c) approximation. The deperturbed rotational constants were also estimated by the perturbation analysis including interaction terms between the ground state and the lowest excited state.
