 Dear Netters,
 I was wondering if anyone had some clues or ideas on how to set up a
 Z-matrix.
 The trouble is that some of my optimizations do not converge to a
 stationary point. However when I make another alternative Z-matrix I
 converge to the Stat. Point. Now my question is : how does one judge,
 given e.g. five different possibilities, which is the best Z-matrix.
 Is this a matter of "Zen" or rather a matter of "science" ?
 Thanks for your time, a summary will be made if useful answers get to me.
