Substituted Benzaldehydes

Experimental electric dipole moments are reported for a number of substituted benzaldehydes (o-, m-, and p-XC6H4CHO; X = NO2, CN, F, Br) as solutes in carbon tetrachloride or benzene at 25�C. Analysis of results yields information concerning the preferred conformations of thesemolecules.

Electric dipole moments and molar Kerr constants are reported for seven organic carbonates (dimethyl carbonate, diethyl carbonate, vinylene carbonate, diphenyl carbonate, di-p-tolyl carbonate, di-o- tolyl carbonate and t-butyl phenyl carbonate) examined as solutes in carbon tetrachloride at 25�. The experimental data are analysed to provide information on the probable solution-state conformations.

Increasing Temperature

The electric dipole moments of six possible rotamers comprising the two diastereomeric forms of 2,5-dimethyl-2,5-dimethoxy-3,4-diphenylhexane have been calculated vectorially. Comparison of these values with the experimental determination of polarization in benzene and carbon tetrachloride shows that only two of the rotamers of the dd,ll form and only one of the meso form are present in significant amount. The moment of the dd,ll diastereomer decreases with increasing temperature but that of the meso form is almost invariant. It is probable that all six central linkages in these diastereomers are hindered from free rotation.

Electric dipole moments and molar Kerr constants are reported for Ph3SiH, Ph3SiCl, (Ph3Si)2O, Ph2SiH2, Ph2SiMe2 and Ph2SiCl2 as solutes in carbon tetrachloride or cyclohexane solution at 298 K. The data are analysed in terms of the preferred solution-state conformations.

The dipole moments of ortho-, meta-, and para-fluoroacetophenone and of ortho-, meta-, and para-trifluoromethylacetophenone were determined in dilute benzene and carbon tetrachloride solutions at 25 °C. In addition the dipole moments and the total energies of the above molecules and of acetophenone, fluorobenzene, and trifluoromethylbenzene were computed for different molecular conformations by the INDO molecular orbital approximation. In some cases there is quantitative agreement between the experimental dipole moments and the INDO computed dipole moments. The most probable conformation for different fluoroacetophenone and trifluoromethylacetophenone molecules is suggested.

The difference in total polarization (ΔP) or dipole moment (ΔP) of 2- benzyl-pyridine, 4-benzylpyridine, diphenyl-2-pyridylmethane, diphenyl- 3-pyridylmethane, or diphenyl-4-pyridylmethane in carbon tetrachloride relative to benzene solution provides evidence of weak interaction between these amines and the former solvent. The molar Kerr constants of the amines in the two solvents for 4-benzylpyridine and diphenyl-4- pyridylmethane are analysed to yield the preferred angles of orientation of the phenyl and 4-pyridyl rings in these two molecules.

Abstract Electric dipole moments are sensitive probes of new phases in the Higgs Yukawa couplings. We calculate the complete two-loop QCD anomalous dimension matrix for the mixing of CP-odd scalar and tensor operators and apply our results for a phenomenological study of CP violation in the bottom and charm Yukawa couplings. We find large shifts of the induced Wilson coefficients at next-to-leading-logarithmic order. Using the experimental bound on the electric dipole moments of the neutron and mercury, we update the constraints on CP-violating phases in the bottom and charm quark Yukawas.
