 Dear All
 I calculated the MEP map of a small molecule using G03. In the map
 visualization using Gaussview3, I set the scale from -4 to -3 to get a multi-
 colour image (ranging from deep red to deep blue). Setting the scale from -4 to
 -3 without crossing over the zero worries me, does it mean whole the molecule
 has a negative electrostatic potential? Can I compare the MEP maps scaled at
 various ranges and calculated at different levels?
 How can I create the MEP using MOPAC 2009 and which program can be used to
 visualize the map?
 Thanks
 Eliac
