The main difficulty of the one-electron theory of optical activity lies in the calculation of the so-called vicinal actions. This may be overcome, as suggested in the present investiga- tion by assuming that the vicinal actions are due to the interactions of various chemical bonds in the molecule with the chromophoric electron. For the calculation of these interactions the charge distribution of a single covalent bond is assumed to consist of two nuclei, each of unit positive charge, separated by the bond distance...

The main difficulty of the one-electron theory of optical activity lies in the calculation of the so-called vicinal actions. This may be overcome, as suggested in the present investiga- tion by assuming that the vicinal actions are due to the interactions of various chemical bonds in the molecule with the chromophoric electron. For the calculation of these interactions the charge distribution of a single covalent bond is assumed to consist of two nuclei, each of unit positive charge, separated by the bond distance and two electrons with opposite spins and a spherically symmetrical orbital eigenfunction represented by (?) where r is the distance measured from a certain point on the bond axis and near the center of the bond. The location of this point is so determined that the model will give the proper dipole moment of the bond. The exponent α, which determines the extent of diffusivity of the electron cloud, is obtained by an approximate variational treatment. The quadruple moment of this model, calculated for the C-H bond, agrees very well with that estimated by Lassettre and Dean from a study of the potential barrier hindering the internal rotation of the ethane molecule. To test the theory and also to illustrate the procedure which is followed in calculating optical rotations using the new model of vicinal actions, the optical rotations of several methyl derivatives of cyclopentanone have been calculated and the following conclusions have been reached: (1) The proposed model gives rise to optical rotations in agreement with the observed values. (2) The effect of the internal rotation of the methyl group on the molecular rotation [M]_D of 3-methylcyclopentanone is large, [M]_D being +44° and -130° for the cis- trans-conformations, respectively. (3) The observed [M]_D may be regarded as composed of two parts, namely, the contribution from the multipole terms and that from the orbital overlapping. The latter corresponds to the "incomplete screening of atomic nuclei", and has been regarded as the most important vicinal action in earlier calculations. In the present work, it is shown, however, that this effect contributes only a few percent of the total [M]_D, unless the perturbing group is very near to the chromophoric group as it is in the case of 2-methyl- cyclopentanone. The failure of the previous calculations is, therefore, due mainly to the omission of the multipole (especially the quadrupole) terms. (4) The absolute configuration of 3-methylcyclopentanone, indicated by the present calculation, is the opposite of the one suggested by Eyring, since he based on the overlapping contribution alone, which bears a sign opposite to that of the total [M]_D (5) That the observed [M]_D of 2,4,5,5-tetramethylcyclopentanone is considerably smaller than that of 2,4-dimethylcyclopentanone may be due to one or both of the following possibilities: (a) that the conformation of the 2- and 4-methyl groups slightly deviates from the trans-position in the tetra-methyl compound, due to the presence of the two additional methyl groups; (b) that the two additional methyl groups in 5,5-positions are not exactly symmetrical with respect to the ring so that they make contributions to [M]_D.

This article consists of three parts. In the first part, based upon the practical requirement for the operation time of relay contacts, the author improved the state model of Moore and Shannon and established a new model. Through theoretical analysis of the new model, it has been proved that the new criterion for measuring the reliability of relay circuit should be the simultaneous fulfilment of the following two inequalities: R (q~(1),q~(2))>1-δ, R (s~(2),s~(1))>1-δ.
