Low Mode Search. An Efficient, Automated Computational Method for Conformational Analysis:  Application to Cyclic and Acyclic Alkanes and Cyclic Peptides

Abstract: The location of energy minima on the conformational energy surface of molecules by computational methods (conformational searching) continues to play a key role in computer-assisted molecular modeling. Although a number of conformational search procedures have been devised over the past several years, new more efficient methods are urgently needed if molecules with increased complexity are to be treated in a quantitative manner. In this paper we describe a method, termed low-mode search (LMOD), which is based … Show more

“…Due to the greater flexibility of the cocaine molecule, the CSP method was adapted to include an automated conformer search: conformations were generated using the low-mode search method 54 and the all-atom optimized potentials for liquid simulations (OPLS-aa) force field 55 . The most stable resulting conformations were refined using constrained B3LYP/6-31G(d,p) geometry optimisations and 16 starting conformations were selected for crystal structure generation.…”
