Semirigorous bounds for the dipole moments and transition moments of the LiH molecule
The Journal of Chemical Physics, 1978Weinhold’s formula for the upper and lower bounds to transition moments is extended to include transitions between states of the same symmetry. Chong’s semirigorous expression for the lower bound to the overlap between the approximate and the true wavefunctions is studied and applied to the calculation of error limits for the dipole moments and ...

Calculation of transition dipole moment in fluorescent proteins--towards efficient energy transfer.
Physical Chemistry, Chemical Physics - PCCP, 2012Förster Resonance Energy Transfer (FRET) between fluorescent proteins (FPs) is widely used to construct fluorescent sensor proteins, to study intracellular protein-protein interactions and to monitor conformational changes in multidomain proteins ...

A note on the transition dipole moment of alkali dimers
The Journal of Chemical Physics, 1981A correlation is observed between the dipole moment D and the frequency ν of the Li2 and Na2 X → A and X → B transitions: the product D2(R)ν(R) is. independent of the internuclear separation R. This is used to predict D(R) for the X → A and X → B transitions of K2. (AIP)

The dipole moment and infrared transition strengths of nitric oxide
The Journal of Chemical Physics, 1998The electric dipole moment function for NO(X 2Π) is determined by nonlinear least-squares analysis of experimental data, including previously reported (Δv=2)/(Δv=1) transition branching ratios for v′⩽13. Polynomial fits to the dipole moment function are determined over the range of internuclear separation from 0.97 to 1.50 Å.

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 ...

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 ...

The transition dipole moment of the ν2 band of the methyl radical
The Journal of Chemical Physics, 1983By using a tunable diode laser, the decay of the absorption intensity with time, after the discharge generating the radical was switched off, was measured for a line [Q4(4)] of the CH3 ν2 fundamental band. When combined with a literature value of the CH3 recombination rate constant, the present result gave an estimate for the steady-state concentration

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.

Origin of transition dipole-moment polarizability and hyperpolarizability in hydrazones
Physical Review B, 2003The origin of transition dipole-moment polarizability and hyperpolarizability in organic materials was investigated using electroabsorption (EA) spectroscopy. It is well established that the following three nonlinear optical properties can be derived from the analysis of EA spectrum; (1) the transition dipole-moment polarizability and ...

Configuration mixing effects on molecular dipole transition moments
Chemical Physics Letters, 1974Abstract The behavior of dipole transition matrix elements between adiabatic eigenstates of diatomic molecules is explored in the region of large configuration mixing. It is demonstrated that the matrix element has a lorentzian shape as a function of internuclear distance. The effect of this shape on the spectrum of LiH is investigated.
