Informed by the belief that making films is an art-and that
watching films is also an art. With an emphasis on the narrative
film, it challenges students to take their film experience further
by sharpening their powers of observation, developing the skills
and habits of perceptive watching, and discovering complex aspects
of film art that they might otherwise overlook. This new edition
presents an organised framework that can be applied to all movies.
"Imagination and shrewd guesswork are powerful instruments for
acquiring scientific knowledge . . . " 1. H. van't Hoff The last
decades have witnessed a rapid growth of quantum chemistry and a
tremendous increase in the number of very accurate ab initio
calculations of the electronic structure of molecules yielding
results of admirable accuracy. This dramatic progress has opened a
new stage in the quantum mechanical description of matter at the
molecular level. In the first place, highly accurate results
provide severe tests of the quantum mecha nics. Secondly, modern
quantitative computational ab initio methods can be synergetically
combined with various experimen tal techniques thus enabling
precise numerical characterization of molecular properties better
than ever anticipated earlier. However, the role of theory is not
exhausted in disclosing the fundamental laws of Nature and
production of ever increasing sets of data of high accuracy. It has
to provide additionally a means of systematization, recognition of
regularities, and ratio nalization of the myriads of established
facts avoiding in this way complete chaos. Additional problems are
represented by molecular wavefunctions provided by the modern
high-level computational quantum chemistry methods. They involve,
in principle, all the information on molecular system, but they are
so immensely complex that can not be immediately understood in
simple and physically meaningful terms. Both of these aspects,
categorization and interpretation, call for conceptual models which
should be preferably pictorial, transparent, intuitively appealing
and well-founded, being sometimes useful for semi quantitative
purposes."
The renowned theoretical physicist Victor F. Weisskopf rightly
pointed out that a real understanding of natural phenomena implies
a clear distinction between the essential and the peripheral. Only
when we reach such an understanding - that is to say when we are
able to separate the relevant from the irrelevant, will the
phenomena no longer appear complex, but intelectually transparent.
This statement, which is generally valid, reflects the very essence
ofmodelling in the quantum theory of matter, on the molecular level
in particular. Indeed, without theoretical models one would be
swamped by too many details embodied in intricate accurate
molecular wavefunctions. Further, physically justified
simplificqtions enable studies of the otherwise intractable systems
and/or phenomena. Finally, a lack of appropriate models would leave
myriads of raw experimental data totally unrelated and
incomprehensible. The present series ofbooks dwells on the most
important models of chemical bonding and on the variety of its
manifestations. In this volume the electronic structure and
properties of molecules are considered in depth. Particular
attention is focused on the nature of intramolecular interactions
which in turn are revealed by various types ofmolecular
spectroscopy. Emphasis is put on the conceptual and interpretive
aspects of the theory in line with the general philosophy adopted
in the series."
