Rotational transitions and electric dipole moment of fluorocarbene, HCF

Journal of Molecular Structure, 2000
Abstract 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 ...

Calculation of the potential energies and transition dipole moments of the CdHg pair

Chemical Physics Letters, 1992
Abstract Potential energies for the ground state and several excited states of the CdHg system have been calculated using the MRCI(SD) procedure for the valence electrons, while all the core electrons are represented by semi-empirical l -dependent pseudopotentials. The effect of spin—orbit coupling has not been investigated.

Variational Upper and Lower Bounds to Dipole Transition Moments

Physical Review Letters, 1970
Electric-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.

Precise determination of electric dipole moment in atomic transitions

AIP Conference Proceedings, 1996
Most 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.

Orientation of Transition Dipole Moments of Phosphorescent Dyes in OLEDs

Light, Energy and the Environment, 2014
In this talk, we will firstly present the influence of the molecular structure of iridium complexes and host materials on the orientation of the TDM in organic semiconductor layers in phosphorescent dye doped organic layers. Secondly we will show through quantum chemical calculations that the heteroleptic structure and the strong intermolecular ...

On the Theory of Magnetic Dipole Moments of Spherical and Transitional Nuclei

1971
R.A. Sorensen, in his invited paper on nuclear moments at the Asilomar Conference, stated that ‘in the continuing contest of experimentalist versus theorist, the experimentalist seems to be in the lead’. After three years this statement seems to be even more justified as the number of experimental data on nuclear magnetic moments and their accuracy ...
