The dielectric properties of horse hemoglobin have been investigated in the frequency range for 100 kcps to 15 Mcps at varying degrees of oxygenation. A linear dependence of the specific increment on the degree of oxygenation wae found under a variety of experimental conditions, the increment of oxy

The aniline molecule is nonplanar, with its NH 2 group lying at an angle ΞΈ of approximately 42 β’ to the plane of the benzene ring. Substituents on the phenyl ring alter this out-of-plane angle as well as other molecular properties such as the ring bond lengths and angles, the barrier to inversion E
## Abstract ^1^H NMR spectra of 26 substituted chalcones (3βarylβ1 phenylβ2βpropeneβ1βones and 1βarylβ3βphenylβ2βpropeneβ1βones) have been studied. The chemical shifts of the Ξ± and Ξ² protons to the carbonyl group were correlated with Hammett sΜ parameters. To gain information on the effect of the t
