If dark matter (DM) has non-zero direct or transition, electric or magnetic dipole moment then it can scatter nucleons electromagnetically in direct detection experiments. Using the results from experiments like XENON, CDMS, DAMA and COGENT we put bounds on the electric and magnetic dipole moments of DM. If DM consists of Dirac fermions with direct dipole moments, then DM of mass less than 10 G...

We show that for asymptotically vanishing Maxwell fields in Minkowski space with non-vanishing total charge, one can find a unique geometric structure, a null direction field, at null infinity.. From this structure a unique complex analytic world-line in complex Minkowski space that can be found and then identified as the complex center of charge. By ”sitting” in an imaginary sense, on this wor...

Sequential Monte Carlo and quantum mechanical calculations of the electronic polarization of the ground and first vertical excited states of 1H-benzotriazole in water are made. Using statistically uncorrelated configurations and CASSCF ab initio calculations the increase in the ground and excited state dipole moments of 1Hbenzotriazole from gas phase to aqueous environment are obtained as 2.89 ...

in this work, we calculated the several physico chemical properties containing of solubility (byvcl), lipophilicity (by milinspiration), dipole and quadrupole moments (by density functionaltheory) for 7 azt analogs, and compared these parameters with inhibition assays of them. it isresulted; cytotoxicity of these drugs is related with their lipophilicity inversely. with using of thisresult, for...

We show that in the MSSM without R-parity symmetry there are no new contributions to electron and neutron electric dipole moments (EDMs) at 1-loop induced by the R-parity violating Yukawa couplings. Non-zero EDMs for the electron and neutron first arise at the 2-loop level. As an example we estimate the contribution of a two-loop graph which induces electron EDMs. On the other hand, we show tha...

Fluorescence imaging is used to visualize directly the transfer of two inner hydrogen atoms in single porphycene molecules. This reaction leads to a chemically equivalent but differently oriented structure and hence results in a rotation of the transition dipole moments. By probing single immobilized molecules with an azimuthally polarized laser beam in the focal spot of a confocal microscope w...

Important information about a geometrical transformation of solute molecules undergoing charge transfer in the excited state could be obtained from the knowledge of its dipole moment change in time, while experimental methods allow to obtain only stationary values of dipole moments for both the local excited and the charge transfer states. On the basis of the theory of solvatochromism the relat...

Dipole Moments, Diazoketones, Thermodynamic, Dielectric Measurements The electric dipole moments of acetyldiazomethane (MeCOCHN2) and 1-acetyl-1-diazoethane (MeCOCMeN2) between 10 and 70 °C have been measured. Using appropriate group and bond moments, the concentrations of the two rotamers present in each have been calculated and, hence, the equilibrium constant for the cis trans equilibrium at...
