![]() ![]() Many new physical methods and techni-ques, which have made it possible, forexample, to study short-lived reactiveintermediates by direct spectroscopicobservations, or to follow the progressof chemical reactions in real time.Another development is that, thanks tofaster computers and better computa-tional methods, organic chemistry hasbecome increasingly theoretical, sinceorganic chemists can now perform directcalculations on interesting moleculesand theoretical problems. The classic textbook Physical-Organic Chemistry, by Neil Isaacs, whichwas published in 1987, provided a com-prehensive treatment of the latestknowledge of the subject at that time.However, since then, especially in thelast two decades, physical-organicchemistry has made enormous advances.One aspect of that is the development of The understandingof the quantitative relationshipsbetween structure and reactivity proper-ties of organic molecules that has comefrom such studies now forms a funda-mental part of every basic lecturecourse. Evidence ofthat trend can be seen, for example, inthe groundbreaking experimental stud-ies of the mechanisms of fundamentalprocesses such as SN1 and SN2 reactions(e.g., the work of Ingold and of Win-stein), or in the development of thetheory of pericyclic reactions (Wood-ward and Hoffman).
