This volume is an autobiography of Michael Dewar, eminent developer of the semi-empirical method of theoretical/computational chemistry.
Michael James Steuart Dewar,
1992

Computational Chemistry: Introduction to the Theory and ...
M.J.S. Dewar, A Semiempirical Life, 1992 Abstract Semiempirical quantum
mechanical calculations are based on the Schr€odinger equation. This chapter
deals with SCF semiempirical methods, in which repeated diagonalization of the
Fock ...

Computational Chemistry: A Practical Guide for Applying ...
4 Semiempirical Methods Semiempirical calculations are set up with the same
general structure as a HF calculation in that they have a Hamiltonian and a wave
function. Within this framework, certain pieces of information are approximated or
...

Computational Chemistry and Molecular Modeling: Principles ...
Semiempirical calculations are much faster than their ab initio counterparts. Their
results, however, can be very wrong if the molecule being computed is not similar
enough to the molecules in the database used to parameterize the method.
K. I. Ramachandran, Gopakumar Deepa, Krishnan Namboori,
2008

Computational Medicinal Chemistry for Drug Discovery
Several methods to reduce this effort have been developed for semiempirical
methods (since they experienced this difficulty much earlier than first-principles
methods). Stewart et al. [145] proposed a simplified diagonalization procedure
based ...

Theory and Applications of Computational Chemistry: The ...
We shall only list some methodological issues that had to be resolved in the
development of semiempirical QM/MM methods. These include the choice of a
proper QM/MM coupling scheme [105] (mechanical, electronic, polarized, ...
Clifford Dykstra, Gernot Frenking, Kwang Kim,
2011

Non-covalent Interactions: Theory and Experiment
In the case of semiempirical QM methods the situation is even more difficult since
here some portion of the correlation energy (via empirical parameters) is covered
. The first attempt to include the dispersion energy into semiempirical QM ...
Pavel Hobza, Klaus Müller-Dethlefs,
2010

Advances in Chemical Physics, New Methods in Computational ...
Whenever such calculations provide a realistic description, the underlying
semiempirical model can be used for explaining and predicting chemical
behavior in terms of simple qualitative concepts. Current developments in
semiempirical ...
I. Prigogine, Stuart A. Rice,
2009

Computational Modeling of Polymers
In this case, one generally uses semiempirical methods to evaluate the rest of the
integrals from experimental data and thus to correct the errors introduced by the
neglect of the noncalculated integrals. In general, semiempirical methods are ...

Genetic Algorithms and Genetic Programming for Multiscale ...
5.3.8 Semiempirical parameter interactions The multiobjective optimization of the
semiempirical parameters for ethylene resulted in 61 different optimal parameter
sets. Figure 5.16 depicts the histogram of the deviation of the 11 semiempirical ...
