Huckel NO computations were rapidly succeeded by semiempirical monodeterminantal Self Consistent Field (SCF) MO calculations which now give way to high quality ab initio calculations of the poly-determinantal SCF-MO and Generalized VB variety. By contrast. no analogous progress has been made in the area of the qualitative theo~ of chemical bonding. In fact. more than a half-centu~ after the exposition of HUckel MO theory the conceptual superstructure of chemist~ is still founded on it. This is made glaringly evident by the fact that highly sophisticated computations are still interpreted with primitive HUckel MO theory. despite the fact that most chemists are well aware of its formal deficiencies. The current popularity Qf qual1tati. ve MO theory among experimental i sts is not the resul t ~f fonnai -advances ~Wt, rather the consequence of stimulating application of old MO theoreti~a. 1 ~oncepts. : . . \" This work attemps to improve this situation by outlining a~t. iJlitative theory of chemical bonding which operates at a high level of theoretical sophistication.\nIt was first presented at the NATO Advanced Study Institute on \"Topics in Theoretical Organic Chemistry\" in Gargnano.

This book is here to warn you about something even more certain than either of those, THE COMING JUDGMENT  This book is not only here to warn you about this coming judgment, but it is also here to help you prepare for it. If we are properly prepared, this coming judgment need not be a time of fear and dread. Learn how you can prepare to meet this coming judgment with boldness and confidence. Every Christian should read this book carefully to make sure they have not been deceived, and to ensure that they are properly prepared for . . . THE COMING JUDGMENT  The Apostle Paul wrote to Christians warning them about this coming judgment and encouraging them to be prepared for it: For we must all appear before the judgment seat of Christ, so that each of us may receive what is due us for the things done while in the body, whether good or bad. I Corinthians 5:10 Therefore be careful how you walk, not as unwise men but as wise, making the most of your time.
