Lasers and chemical change is the study of radiation and molecules
in dis equilibrium. The distinguishing feature of such systems is
the extreme de parture from thermal equilibrium: the radiation is
usually confined to a narrow frequency range, is well coll imated,
and is far brighter than black body radiation; the chemical
composition and also the distribution of mole cules over their
different energy states are often markedly displaced from that
expected at equilibrium. Such systems can be used as a source of
laser radiation and, reversedly, lasers can rapidly and selectively
displace mole cular systems from equilibrium. The subsequent
evolution of the initially prepared state can then be monitored -
again using lasers. One purpose of this book is to introduce the
concepts required to d- cuss systems of radiation and molecules in
disequilibrium. These include the physics of (laser) radiation and
of radiation-matter interaction and molecular structure and
spectroscopy. Excellent textbooks of these topics are available and
our survey (in Chap. 3) is only intended to accent the es sential
points, with special reference to atomic and molecular radiation
physics. Considerably more attention is given to the topic of
disequilibrium in chemical systems (Chap. 2). In particular we
consider both inter- and intra molecular dynamics with special
reference to energy requirements and energy disposal in chemical
reactions and to what goes on in between - intramole cular energy
migration."
