The problem of a relativistic spin 1/2 particle confined to one-dimensional box is solved in way that resembles closely the solution well known quantum-mechanical textbook non-relativistic box. energy levels and probability density are computed compared with case.
The effect of substituents on 13C-H coupling constants is discussed, within the framework Pople-Santry MO theory nuclear spin coupling, by making a theoretical analysis contributions due to differences coulomb and resonance integrals as well presence electron lone-pairs. Earlier treatments based correlations J CH with s characters are shown be less justified mainly because description bonds in terms localized MO's not valid, no physical meaning can rigorously attributed concepts such rehybridization.
Abstract A comparative study of the proton magnetic resonance spectra mono-, di-, tri- and tetra-t-butyl methyl substituted benzenes shows that a t-butyl group interacts with ring as strongly group. Low-field chemical shifts protons (amounting to -0·50 p.p.m.) -0·23 ortho are attributed intramolecular van der Waals forces. The possibility severe puckering in t-butylbenzenes is rejected since it felt this phenomenon should produce high-field signals. Additional informationNotes on...
Abstract A study of the proton N.M.R. spectra (aza)biphenyls at several temperatures and in various solvents has shown that planarity these molecules increases series biphenyl, 2‐phenylpyridine, 2‐phenylpyrimidine 2,2′‐bipyridyl, latter compound being mainly trans room temperature. It follows an ortho‐ortho CH… N interaction is less repulsive than a corresponding CH interaction. Rapid rotation having one o ‐nitrogen atom found to persist −65 °C.
