Kerr Constants

Electric dipole moments and molar Kerr constants are reported for ammonia, trimethylamine, trimethylamine oxide, 1,4- diazabicyclo[2,2,2]octane and its monohydrate in non-polar solvents. The dipole moment now found for 1,4-diazabicyclo[2,2,2]octane differs substantially from previously recorded values. Effective polarizability anisotropies are derived for each of the anhydrous molecules and for the N-H and N-C bonds. The effect of solute interactions with benzene is explored.

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.

Light from the high-field region of a Lo Surdo discharge in ammonia was focused on the slit of a stigmatic spectrograph. Spectrograms of the 3 360 and 3 240 Å bands of NH and the hydrogen line Hβ were taken simultaneously. From observations of the molecular and atomic hydrogen Stark splittings and intensities the electric dipole moments of the degenerate states of NH were determined to be μ(A3Π) = (1.31 ± 0.03), μ(c1Π) = (1.70 ± 0.07), μ (a1Δ) = 1.49 ± 0.06) Debye, where the signs of μ(c1Π.) and μ(a1Δ) are the same.
