| simulated annealing | Starting with an extended structure, 100 structures were generated using a simulated annealing protocol. This was followed by 18000 steps of simulated annealing at 1000 K and a subsequent decrease in temperature in 6000 steps in the first slow-cool annealing stage. | NMRDraw |
