LSD

This is a representation of the minimum energy conformer of LSD free base. Minimization was carried out in a vacuum (i.e. without any solvent molecules around the molecule), 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 electron density surface of the molecule is rendered as a grey mesh surface. The molecular electrostatic potential (MEP) has been plotted on the least squares plane of the molecule as a series of contour lines. Finally, volumes representing the highest occupied molecular orbital (HOMO) are also plotted on the molecule. The phases of the lobes of the HOMO are represented either as blue or red.
