“…Such transition has received significant attention among the other zinc monohalides ever since the demonstration of the ZnI lasing. 17 Our spectroscopic constants of the excited 2 Σ + states are compared to those computed theoretically. 10,11 Although diabatic approximation has yielded better vibrational frequency of the (2) 2 Π state, reasonable agreements are shown for the other constants.…”

Adiabatic potential energy curves of the 28 low-lying doublet and quartet electronic states in the representation 2s+1Λ(±) of the zinc monofluoride molecule are investigated using the complete active space self-consistent field (CASSCF) with multi-reference configuration interaction (MRCI) method including single and double excitations with the Davidson correction (+Q). The internuclear distance Re, the harmonic frequency ωe, the static and transition dipole moment μ, the rotational constant Be, and the electronic transition energy with respect to the ground state Te are calculated for the bound states. The transition dipole moment between some doublet states is used to determine the Einstein spontaneous A21 and induced emission [Formula: see text] coefficients, as well as the spontaneous radiative lifetime τspon, emission wavelength λ21, and oscillator strength f21. The ground state ionicity qionicity and equilibrium dissociation energy DE,e are also computed. The comparison between the values of the present work and those available in the literature for several electronic states shows very good agreement. Twenty-three new electronic states have been studied in the present work for the first time.

“…The potentials energy curves of the low lying states of CdBr and CdI are presented in figures (5)(6)(7)(8). It is found that the electronic ground states of CdBr and CdI is the X 2 Σ + state with R e = 2.564 Å and R e = 2.749 Å respectively.…”

“…The analogy between the transitions of ZnI and CdI [8][9][10][11] and those that are demonstrated on the bluegreen lasing on the transition between B 2 Σ + -X 2 Σ + of mercury mono-halides [12][13][14][15][16] inspired studies on the composing molecules of such laser systems. Inspired by the similarity between the valence electronic structure of cadmium monohalides and the first exploratory laser-cooled SrF diatomic 17,18 with the 3d orbitals fully occupied, we are encouraged to investigate the low-lying electronic states of cadmium monohalides.…”

The potential energy and dipole moment curves for the lowest electronic states in the representation 2s+1 Λ (±) of CdX (X = F, Cl, Br, I) molecules are investigated via complete active space self-consistent field (CASSCF) and multi-reference configuration interaction MRCI (single and double excitation with Davidson correction). For the bound states of CdX diatomic molecules the bond distances R e , the vibrational harmonic frequencies ω e , the rotational constants B e , the electronic energies relative to the ground state T e , and the permanent and transition dipole moments have been computed. The dissociation energy limits of the atomic levels of CdX compounds are also calculated. The transition dipole moment between the ground state X 2 Σ + and (2) 2 Σ + is investigated. Consequently, the transition dipole moment values of the upper state at its equilibrium position | µ 21 |, the emission angular frequency ω 21 , the Einstein coefficients of spontaneous and induced emissions (A 21 and B ω 21 ), the spontaneous radiative lifetime τ spon , the emission cross section σ 0 , the line strength and the emission oscillator strength f 21 are calculated along with the ionicity of the X 2 Σ + and (2)

“…The demonstration of the blue-green lasing on the B 2 Σ þ -X 2 Σ þ transition of mercury mono-halides [1][2][3][4][5] and the analogous transitions of ZnI and CdI [6][7][8] have motivated subsequent studies to be carried out on such laser systems and their composing molecules. Lipson and his coworker [9] presented the fluorescence excitation spectra of ZnI from which the potential energy curves of the three lowlying spin-orbit states and the equilibrium bond length of the B 2 Σ þ state were reported.…”
