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.

The One

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.
