General classical equation of spin motion is explicitly derived for a particle with magnetic and electric dipole moments in electromagnetic fields. Equation describing the spin motion relative to the momentum direction in storage rings is also obtained.

Stark-effect measurements on pure rotational transitions of TlBr and Til are described. The derived electric dipole moments of the most abundant isotopic molecules on the ground vibrational state are:205TL79Br : | μ0| = (4.493 ± 0.050) D , 205Tl127 I | μ 0| =(4.607 ± 0.070) D .The electric dipole moment of 205Tl19F | μ 0|=4.2282 (8) D was used as standard.

We dicuss the utility of precision probes for flavour-diagonal CP-violation, namely, searches for electric dipole moments of nucleons, atoms, and molecules, in looking for new physics thresholds that manifest themselves primarily through higher dimensional operators. After reviewing the status of the electric dipole moment (EDM) constraints, we consider first the sensitivity to a generic class of dimension-five operators generated at a supersymmetric threshold, through their contribution to CP- and flavour-violating observables. Such thresholds can be probed by EDMs up to a scale of order 108 GeV depending on the flavour structure. We then turn to consider the possibility that electroweak baryogenesis is made feasible by the introduction of dimension-six operators at a TeV-scale threshold. The EDM costraints on dimension-six couplings of the Higgs to the fermions currently still allow a reasonable window in parameter space for these models, but the next generation of experiments should provide a conclusive test.

We study the charged lepton electric dipole moment which is induced by the scalar unparticle mediation and we predict the appropriate range for the free parameters appearing in the effective Lagrangian which drives the unparticle-standard model lepton interactions. We observe that the charged lepton electric dipole moment is strongly sensitive to the scaling dimension du of the unparticle and the new couplings in the effective interaction. Furthermore, we see that the current experimental limits of charged lepton electric dipole moments can ensure an appropriate range for these free parameters.

In the present study we investigated the permanent electric dipole moment and other properties of several alkali–alkaline earth molecules in the lowest Σ+ state of the doublet and quartet multiplicity.

Of the methods which have been devised for the measurement of angles between covalencies, the one based on measurements of electric dipole moments is among the most valuable. Descriptions of considerable experimental work on the subject have been published by several authors, but the discussions of the basis of the method, its further possible applications, the possible errors and their probable importance, are not only scattered, but incomplete. It therefore appeared desirable that a more complete, general treatment of these matters should be given, and the present communication is an attempt to do this.

Mössbauer spectra and electric dipole moment data are reported for R2SnCl2 and RSnCl3 complexes with Y type ligands where R = C4H9, C6H5 and Y = Ph3PO, Ph3AsO, Bu3PO, and Ph3P. Quadrupole splittings and dipole moments are consistent with trans C—Sn—C bonds in the R2SnQ2Y2 complexes. In the trigonal bipyramidal Ph2SnCl2Y complexes, the two phenyl groups are assumed to be in equatorial positions. Data for the RSnCl3Y2 complexes suggest that in BuSnCl3(Ph3AsO)2 and BuSnCl3-(Ph3P)2 two Cl atoms are trans and that in BuSnCl3(Ph3PO)2 and PhSnCl3(Ph3PO)2 the three Cl atoms are cis.

AbstractThe rotation of a spherical particle in a constant electric field (an effect found earlier) has been analyzed. The particle is illuminated to induce the electric dipole moment of the sphere. The dynamics of the rotation effect has been considered in general terms to refine conditions for adiabatic rotation. The features of the particle’s nonadiabatic rotation have been demonstrated with a sphere placed in a medium with an infinitesimal viscosity. It has been shown that the nonadiabatic rotation dynamics to a great extent depends on a relationship between the electrical and photoinduced dipole moments of the sphere. The rotation dynamics of a particle with a slightly nonspherical shape has been briefly analyzed.
