Over the last twenty years, developments of the ab initio metho- dologies and of the computing capacities have progressively turned quantum chemistry into a predictive tool for molecular systems involving only light elements.

The calculation of cross sections and rate constants for chemical reactions in the gas phase has long been a major problem in theoretical chemistry.

ENVIRONMENTAL MANAGEMENT SERIES The current expansion of both public and scientific interest in environ- mental issues has not been accompanied by a commensurate production of adequate books, and those which are available are widely variable in approach and depth.

The Twentieth Jerusalem Symposium reflected the high standards of these distinguished scientific meetings which convene once a year at the Israel Academy of Sciences and Humanities in Jerusalem to discuss a specific topic in the broad area of quantum chemistry and biochemistry.

'The criterion of true beauty' , wrote Fulke Greville, 1st Baron of Burke, 'is that it increases on examination; if false, that it lessens.

The aim of this Workshop on "e;Selectivity in Chemical Reactions"e; was to examine the specific preferences exhibited by simple chemical reactions with regards to reagents having particular energy states, symmetries, alignment and orientation and the resulting formation of certain products with their corresponding energies, states, alignment and polarisation.

Ordered systems exhibit physical properties and behavior unknown in media where structural ordering and organization do not take place.
