Progress toward attaining an accurate solution of the Schr”dinger equation has occurred in spurts, with fully convergent solutions of a number of systems having appeared recently. One approach that has made this achievement possible is described: the use of the generalized Newton variational principle in which the reactive amplitude density is expanded variationally in a basis set of integral functions.

Recent progress in molecular biology and in high-field pulse-programmed nuclear magnetic resonance spectroscopy have allowed accelerated progress in mapping the biosynthesis of important biologically active molecules. A summary describes how these tools have provided recent insight into the routes nature uses to assemble B12 and its coenzymes.
