The Advanced Study Institute on "Quantum Dynamics of Molecules: The New
Experimental Challenge to Theorists," which was sponsored by the
Scientific Affairs Division of NATO, was held at Trinity Hall, Ca
bridge, England from September 15th till September 29th, 1979. In all, a
total of 79 lecturers and students attended the meeting: they had
diverse backgrounds in chemistry, physics and mathematics. In my
proposal to NATO requesting financial support for an Advanced Study
Institute, I suggested that molecular physics was facing a qualitatively
new experimental situation in which the exploration of previously
inaccessible dynamical phenomena would become of increasing importance.
At the same time I was aware that in recent years powerful theoretical
techniques, that might prove crucial tools for the interpretation of the
new experiments, have been developed in mathematics and theoretical
physics. The aim of the ASI was to review at an advanced level these
recent developments, juxtaposing new theory with new experimental pos-
sibilities in the hope that the participants in the-Institute would
through their subsequent work increase the awareness of the whole
molecular theory community of the changing nature of chemical physics.
The recent developments in laser spectroscopy, particle scatter- ing
experiments and molecular beam technology imply that an entirely new
class of phenomena involving molecules in gasses and liquids can now be
investigated.
