The low-lying electronic states of the nickel monohalides, ie, NiF, NiCl, NiBr, and NiI, are
investigated by using multireference second-order perturbation theory with relativistic effects …

Four new electronic transitions of NiF, recorded by high-resolution Fourier transform
spectroscopy, have been located in the near infrared spectral region. The three new upper …

For the first time, we have studied the potential-energy curves, spectroscopic terms,
vibrational levels, and the spectroscopic constants of the ground and low-lying excited states …

High-resolution laser-induced fluorescence spectrum of a jet-cooled NiI molecule has been
recorded in the near infrared and visible regions. The NiI molecule was produced by …

Laser-induced fluorescence spectrum of NiI in the near infrared region of 714–770 nm has
been recorded. Seven bands belonging to three electronic transition systems were observed …

In the first part of this paper an effective Hamiltonian for a non-rotating diatomic molecule
containing only crystal-field and spin–orbit operators is set up to describe the energies of the …

Optical spectra of the supersonically cooled NiCCH radical have been recorded in the 530–
650 nm region using the resonant two-photon ionisation method, and five of the observed …

The emission spectrum of NiS has been investigated in the near infrared in the 2000–
7500cm− 1 region using a Fourier transform spectrometer. New bands observed in the 3000 …

The low-lying states of NiCl seem to correlate well with the Ni+(3d9) ClĀ (3p6) electron
configuration. To date, the following low-lying states are known through pure rotational …

Laser induced fluorescence and single vibronic level emission spectroscopy has been used
to probe five low-lying electronic states (X2Π3/2, A2Δ5/2, X2Π1/2, A2Δ3/2 and B2Σ1/2+) of …
