If the Hamiltonian would be the sum of one-electron operators only, one could easily separate the variables in the basic Schrodin-ger equation (Eq. II. 1), and the total wave function 0 would then be the product of N one-particle functions each one being an... 

Thus, the spatial function (q) is actually a set of eigenfunctions t/ n(q) of the Hamiltonian operator H with eigenvalues E . The time-independent Schrodin-ger equation takes the form...

Background Philosophy. Within the framework of the Born-Oppenheimer approximation (JJ ), the solutions of the Schroedin-ger equation, Hf = Ef, introduce the concept of molecular structure and, thereby, the total energy hyperspace provided that the electronic wave function varies only slowly with the nuclear coordinates, electronic energies can be calculated for sets of fixed nuclear positions. The total energies i.e. the sums of electronic energy and the energy due to the electrostatic re-...

A final point about basis functions concerns the way in which their radial parts are represented mathematically. The AOs, obtained from solutions of the Schrbdin-ger equation for one-electron atoms, fall-off exponentially with distance. Unfoitu-nately, if exponentials are used as basis functions, computing the integrals that are required for obtaining electron repulsion energies between electrons is mathematically very cumbersome. Perhaps the most important software development in wave function based calculations came from the realization by Frank Boys that it would be much easier and faster to compute electron repulsion integrals if Gaussian-type functions, rather than exponential functions, were used to represent AOs. 

Kinetite (Kinetit or Kinenite-Swiss). One of the earliest gelatinous (plastic) expls which contd no NG. It was patented in 1884 by Petry and Fallenstein and was used extensively at the end of the last century in Ger and other European countries. It was prepd by gelatinizing Nitrobenzene or Nitrotoluene with Collodion Cotton, and impregnating this plastic mass with sulfur, K chlorate and other ingredients. Sulfur was later replaced by Sb penta-sulfide. Its compn was NB 16.0 to 21.0, Collodion Cotton 0.75 to 1.0, K chlorate 82.5 to 75.0, Sb2Ss and/or K nitrate 3.0 to 1.0%. The function of the Sb pentasulfide was to render the explosion more regular and more complete... 

The A -unsubstituted (3-lactams are important building blocks for the synthesis of several biologically active antibiotics. However, solution phase techniques normally include acidic conditions, which are not tolerable with acid-sensitive functionalities. In an elegant approach, Banik et al. [133] developed a solid phase synthetic route to access A -unsubstituted (3-lactams directly using Rink resin as the solid support. The method for construction of (3-lactam ring was based on Staudin-ger reaction and subsequent cleavage from the solid support was done with TFA in dichloromethane (Scheme 30).
