Progress in Theoretical Chemistry and Physics
Aseries reporting advances in theoretical molecular and material
sciences, including theoretical, mathematical and computational
chemistry, physical chemistry and chemical physics
Aim and Scope
Science progresses by a symbiotic interaction between theory and experiment: theory is
used to interpret experimental results and may suggest new experiments; experiment
helps to test theoretical predictions and may lead to improved theories. Theoretical
Chemistry (including Physical Chemistry and Chemical Physics) provides the concep
tual and technical background and apparatus for the rationalisation of phenomena in the
chemical sciences. It is, therefore, a wide ranging subject, reflecting the diversity of
molecular and related species and processes arising in chemical systems. The book
series Progress in Theoretical Chemistry and Physics aims to report advances in
methods and applications in this extended domain. It will comprise monographs as weil
as collections of papers on particular themes, which may arise from proceedings of
symposia or invited papers on specific topics as weil as initiatives from authors or
translations.
The basic theories of physics - classical mechanics and electromagnetism, relativity
theory, quantum mechanics, statistical mechanics, quantum electrodynamics - support
the theoretical apparatus which is used in molecular sciences. Quantum mechanics
plays a particular role in theoretical chemistry, providing the basis for the valence
theories which allow to interpret the structure of molecules and for the spectroscopic
models employed in the determination of structural information from spectral patterns.
Indeed, Quantum Chemistry often appears synonymous with Theoretical Chemistry: it
will, therefore, constitute a major part of this book series. However, the scope of the
series will also include other areas of theoretical chemistry, such as mathematical
chemistry (which involves the use of algebra and topology in the analysis of molecular
structures and reactions); molecular mechanics, molecular dynamics and chemical
thermodynamics, which play an important role in rationalizing the geometric and
electronic structures of molecular assemblies and polymers, clusters and crystals;
surface, interface, solvent and solid-state effects; excited-state dynamics, reactive
collisions, and chemical reactions.
Recent decades have seen the emergence of a novel approach to scientific research,
based on the exploitation of fast electronic digital computers. Computation provides a
method of investigation which transcends the traditional division between theory and
experiment. Computer-assisted simulation and design may afford a solution to complex
problems which would otherwise be intractable to theoretical analysis, and mayaiso
provide a viable alternative to difficult or costly laboratory experiments. Though
stemming from Theoretical Chemistry, Computational Chemistry is a field of research
v
Progress in Theoretical Chemistry and Physics
in its own right, which can help to test theoretical predictions and mayaiso suggest
improved theories.
The field of theoretical molecular sciences ranges from fundamental physical
questions relevant to the molecular concept, through the statics and dynamics of
isolated molecules, aggregates and materials, molecular properties and interactions, and
the role of molecules in the biological sciences. Therefore, it involves the physical basis
for geometric and electronic structure, states of aggregation, physical and chemical
transformations, thermodynamic and kinetic properties, as weIl as unusual properties
such as extreme flexibility or strong relativistic or quantum-field effects, extreme
conditions such as intense radiation fields or interaction with the continuum, and the
specificity ofbiochemical reactions.
Theoretical chemistry has an applied branch - apart of molecular engineering,
which involves the investigation of structure-property relationships aiming at the
design, synthesis and application of molecules and materials endowed with specific
functions, now in demand in such areas as molecular electronics, drug design or genetic
engineering. Relevant properties include conductivity (normal, semi- and supra-),
magnetism (ferro- or ferri-), optoelectronic effects (involving nonlinear response),
photochromism and photoreactivity, radiation and thermal resistance, molecular recog
nition and information processing, and biological and pharmaceutical activities, as weIl
as properties favouring self-assembling mechanisms and combination properties needed
in multifunctional systems.
Progress in Theoretical Chemistry and Physics is made at different rates in these
various research fields. The aim of this book series is to provide timely and in-depth
coverage of selected topics and broad-ranging yet detailed analysis of contemporary
theories and their applications. The series will be of primary interest to those whose
research is directly concemed with the development and application of theoretical
approaches in the chemical sciences. It will provide up-to-date reports on theoretical
methods for the chemist, thermodynamician or spectroscopist, the atomic, molecular or
cluster physicist, and the biochemist or molecular biologist who wish to employ
techniques developed in theoretical, mathematical or computational chemistry in their
research programmes. It is also intended to provide the graduate student with a readily
accessible documentation on various branches of theoretical chemistry, physical chem
istry and chemical physics.
