LSD - Molecular Electrostatic Potential

The LSD molecule is rendered as an electron probability density isosurface. The color contours represent varying electrostatic potential at the surface and have been modified for aesthetic purposes. The electrostatic potential is most positive in light yellow areas, with red areas neutral, and the dark purple regions most negative. Calculations were performed on a Tektronix CAChe (TM) molecular modeling worksystem: initial molecular mechanics optimization was performed using CAChe's conjugate gradient routine with Allinger's standard MM2 force field parameters. The structure was further refined using CAChe's implemation of the molecular orbital package MOPAC using the AM1 Hamiltonian parameters. The electron density isosurface was generated using CAChe's Tabulator module.
