Showing papers on "Chemical binding published in 1976"
TL;DR: In this paper, an optically transparent semiconductor electrode whose surface was modified by the chemical binding of sensitising dyes was used to obtain a photocurrent as large as those previously observed at the unmodified electrodes in contact with the dye solutions.
Abstract: WE have developed a new type of electrochemical photocell, using an optically transparent semiconductor electrode whose surface was modified by the chemical binding of sensitising dyes. In spite of the absence of dye in the solution, a photocurrent, as large as those previously observed at the unmodified electrodes in contact with the dye solutions was obtained.

TL;DR: In this article, the three-membered ring systems, cyclopropane,cyclopropene and cyclopornone, were investigated using a (9,5,1 ) Gaussian basis set.

TL;DR: In this article, the authors calculated γ 11, a neutron-condensed system energy observable, using the recent neutron scattering kernel proposed by the authors which incorporates explicitly chemical binding amongst the water molecules, turns out to be in much better agreement with the experimental result than that given by the widely used Nelkin kernel.

TL;DR: The description of one or more electrons in the field of two nuclei is one of the fundamental problems in quantum mechanics and it contains the theoretical understanding of the phenomenon of chemical binding and thus is connected physics and chemistry as discussed by the authors.
Abstract: The description of one or more electrons in the field of two nuclei is one of the fundamental problems in quantum mechanics. Among other things it contains the theoretical understanding of the phenomenon of chemical binding and thus is connects physics and chemistry. In 1927 W. Heitler and F. London1 showed for the first time the possibility of the existence of the H2 molecule. They used an approximation procedure and were able to calculate its physical properties (binding energy, binding length).

TL;DR: In this article, the profile of the 1·33 MeV y rays emitted by 6°Ni was deduced from the measured cross sections for resonance scattering of 1· 33 MeVY rays in coincidence with the preceding 1·17 MeVy rays.
Abstract: The energy spectrum of 6°Ni recoils from 60Co fJ decay in a vapour CoBr2 source has been studied by measuring the profile of the 1· 33 MeV y rays emitted by 6°Ni The profile was deduced from the measured cross sections for resonance scattering of the 1· 33 MeV y rays in coincidence with the preceding 1·17 MeV y rays The results show fair agreement with the profile calculated for free 60Co atoms The influence of molecular Coulomb fragmentation and chemical binding are discussed

TL;DR: In this paper, the three-membered ring systems, cyclopropane,cyclopropene and cyclopornone, were investigated using a (9,5,1 ) Gaussian basis set.
Abstract: The three-membered ring systems, cyclopropane, cyclopropene and cyclopropenone, have been investigated using a (9,5,1 ) Gaussian basis set. A detailed study of the chemical binding in these systems has been of particular interest. Results for the molecular ground states have been compared with predictions made previously using smaller basis sets and also with pertinent experimental findings.
