Chem. Phys. 105(1), 192, (1996): "The generation and use of delocalized internal coordinates in geometry optimization"] that describes an efficient algorithm for geometry optimization in delocalized internal coordinates. One of the references there is to a suite of programs by J. Baker called OPTIMIZE, that carries out that particular algorithm. I could not find on the web any trace of neither the author, nor the computer code. I did find that it was incorporated in two commercial products. 1. Does anyone has a pointer to the author of the code or the code itself? 2. Are there free computer codes that implements that algorithm? 3. Are there free computer codes that implement other internal coordinates optimization, such as redundant internal coordinates method? Any suggestions are greatly appreciated, Silviu. -- %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Zilberman Silviu, PhD 213 Frick Laboratory, Department of Chemistry, Princeton University Princeton, NJ 08544, USA phone: 609-258-1834 fax: 609-258-6746 silviu[at]Princeton.EDU %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
