What a splendid site Nick. I have one question. I have for years taught eg pericyclic mechanisms, where I drum home to the students that pushed arrows have three dimensions. Thus suprafacial, antarafacial, etc etc. Its a specific case of the more general stereoelectronic theory of chemistry. This 3D nature is a little tricky to display. for example, I am looking at the 1,3 dipolar cycloaddtion for ozonolysis, where unless I am mistaken, the arrows could be taken to indicate antarafacial on the carbonyl and antarafacial on the 1,3 dipole. Whilst this is actually "allowed", no 4a + 2a cycloaddition is actually known. I must confess to being both impressed and baffled as to how the arrows were generated, but is it possible to show the suprafacial/antarafaciality with greater precision, ie true 3D arrows (after all, Jmol is the only tool for arrow pushing I have ever seen which is capable of doing this!) Generally, how does one go about authoring this? How long would it take to eg position one arrow in a starting set of 3D coordinates? -- Henry Rzepa. +44 (020) 7594 5774 (Voice); +44 (0870) 132 3747 (eFax); [EMAIL PROTECTED] (iChat) http://www.ch.ic.ac.uk/rzepa/ Dept.
