Ayrton, W E (1847-1908) An outstanding teacher of electrical subjects, often using apparatus he had made himself. Appointed the first Professor of Natural Philosophy and Telegraphy at the Imperial College of Engineering, Tokyo in 1873. He became Professor of Electrical Engineering at Finsbury Technical College in 1879 and in 1884 became Professor of Electrical Engineering at the Central Technical College, eventually becoming Dean in 1904. In Tokyo, Ayrton, with John Perry, worked on dialectic constants of gases; viscosities of dialectics and at Finsbury they invented many electrical measuring instruments, including a spiral-spring ammeter and wattmeter. They also worked on railway electrification and produced a dynometer, and in 1882 the first electric tricycle. He was President of the IEE in 1892.

83. 5 Relativistic Effective Core Potentials atomic orbitals is assumed, a priori, so that the total number of parameters whichmust be optimized in, say, the computation of a hartreeFock wavefunction http://zopyros.ccqc.uga.edu/~kellogg/docs/rltvt/node21.html

Next: 5.1 Effective Core Potentials Up: An Introduction to Relativistic Electronic Structure Theory in Previous: 4.3 The Douglas-Kroll Transformation 5 Relativistic Effective Core Potentials One of the most fundamental assumptions in chemistry is that low lying core electrons are relatively inert, and are not perturbed by a molecular environment. This assumption is supported by the chemical similarity of elements in the same column of the periodic table. Most of the important chemical properties of atoms and molecules are determined by the interaction of their valence electrons with the valence electrons of other atomic or molecular species. For molecules containing heavy atoms, large computational savings may be realized if a particular mathematical form for the atomic orbitals is assumed, a priori , so that the total number of parameters which must be optimized in, say, the computation of a Hartree-Fock wavefunction may be reduced. This approximation on its own is known as the frozen core approximation and will be explored in some detail in chapter 3. A more extensive savings may be achieved if, instead of simply assuming a particular form for the core orbitals, all terms describing the interaction of the electrons in these orbitals with each other and those outside the core region are simply replaced by a scalar ``effective potential''. This provides the additional benefit of reducing the basis set size requirements, since no basis functions are now needed to explicitly describe the core orbitals. This has the effect of drastically reducing the number of two-electron quantities, such as electron repulsion integrals, which must be considered.
