Statistical fields in molecules: calculation of the dipole moments of iodine chloride and the carbon-hydrogen bond in methane by the Fermi-Thomas method.
MetadataShow full item record
In the treatment of atoms or molecules with many electrons, the accurate quantum theory involving solution of the wave equation in many dimensional space is far too complicated to be practicable. One must therefore resort to approximate methods. The best of these is Hartree's method of the self-consistent field. Even this is hardly practicable when one has to deal with many electrons, so that a simpler and rougher method is required. The chemist more than the physicist often derives valuable assistance from the semiquantitative sort of information which the cruder methods are capable of yielding. Such a method is provided by the Fermi-Thomas atomic model. This model has been used successfully in the treatment of atoms, but very little attempt has been made to extend this method to the treatment of even the simplest molecules. This research is concerned with the application of this model to two types of simple molecules, the diatomic molecule, exemplified by iodine chloride and the tetrahedral molecule, methane.[TRUNCATED]
