Allowed transitions and the dipole moment of HD+
Chemical Physics Letters, 1974Abstract Within the Born-Oppenheimer approximation homopolar isotopically unsymmetric diatomic ions (HD+, 14N15N+, 35Cl37Cl+, etc.) have D∞h symmetry and a non-vanishing dipole moment. This apparent paradox is reconciled here by treating carefully the transformation properties of the dipole moment operator in the D∞h group.

Improved lower and upper bounds for dipole transition moments
Journal of Physics B: Atomic and Molecular Physics, 1986The effective-bounds formulae for dipole transition moments introduced by Anderson and Weinhold (1974) have been strengthened significantly without altering the approximate wavefunctions by two procedures, each of which modifies the transition operator.

Magnetic moments and magnetic dipole transitions in deformed nuclei
Journal of Physics A: General Physics, 1969See also preceding abstract. The magnetic moments of the lowest rotational states of even-even nuclei and the probabilities of magnetic dipole transitions between these states are calculated on the basis of the model suggested by Krutov in 1968 the non-axiality of the nuclear equilibrium shape and the difference between the mass and charge ...

Permanent and transition dipole moments in CaF and CaCl
The Journal of Chemical Physics, 2001Permanent and transition dipole moments have been calculated for various states of CaF and CaCl by using an effective one-electron variational eigenchannel R-matrix approach combined with generalized quantum defect theory. The ion core dipole moment has been evaluated ab initio.

Rotational transitions and electric dipole moment of fluorocarbene, HCF
Journal of Molecular Structure, 2000Abstract Microwave optical double resonance was used to determine the electric dipole moment components along the axes of inertia of the HCF molecule. The values are μ a =0.043(5) D, and μ b =1.402(6) D. Some of the rotational and centrifugal distortion constants, previously determined from Doppler limited optical spectra, were obtained with ...

Core polarization corrections to magnetic dipole moments and transitions
Zeitschrift für Physik A Hadrons and nuclei, 1973Core polarization corrections to ground state magnetic dipole moments are calculated in first-order perturbation theory, with the use of Sussex matrix elements. These corrections are introduced in the particle-(hole-) core coupling model. It is shown that the need for effectivegs factors in the calculation of magnetic moments can be explained largely ...

Transition dipole moments and probabilities of the CCl radicals
Journal of Quantitative Spectroscopy and Radiative Transfer, 2019Abstract This work studies the transition dipole moments and properties of 12 electronic states. These states are X2Π, A2Δ, B2Σ+, C2Π, 12Σ−, 22Σ−, a4Σ−, b4Π, 14Σ+, 14Δ, 24Π, and 24Σ−; they originate from the first dissociation limit of the carbon monochloride radical.

Precise determination of electric dipole moment in atomic transitions
AIP Conference Proceedings, 1996Most conventional methods of determining the dipole moment μ are unsatisfactory when applied to transitions between degenerate levels; this is because the overlapping of transitions among magnetic sub‐levels modifies the photo‐excitation behavior in a complex way. To overcome this difficulty, two novel methods of determination are presented.

Electromagnetic moments and electric dipole transitions in carbon isotopes
Physical Review C, 2003We carry out shell model calculations to study electromagnetic moments and electric dipole transitions of C isotopes. We point out the configuration dependence of the quadrupole and magnetic moments of the odd C isotopes, which will be useful to find out the deformations and the spin parities of the ground states of these nuclei.

Variational Upper and Lower Bounds to Dipole Transition Moments
Physical Review Letters, 1970Electric-dipole transition moments are calculated by a variational procedure which gives rigorous upper and lower bounds even though the exact wave functions are unknown. The method is applied to the lowest optical transition ($1s\ensuremath{\sigma}\ensuremath{\rightarrow}2p\ensuremath{\sigma}$) of the hydrogen molecule ion, with satisfactory results.
