LSD
This is another representation of the minimum energy conformer of LSD, shown as a ball and spoke model. Minimization was carried out in a vacuum, using semiempirical methods and the AM1 Hamiltonian as implemented in the Spartan software package (v. 4, Wavefunction, Inc) and running on a Silicon Graphics Indigo 2 workstation. The molecular electrostatic potential (MEP) has been mapped onto the electron density dot surface of the molecule. In addition, Spartan has been used to display the MEP as a series of energy contours, displayed on planes perpendicular to the molecular least squares plane.
