    • The Titan software package was used to perform the analysis. The "Conformer Study" option was selected as a computation type, and PM3 was selected as the method, the results in conformations being generated using the included MMFF94 molecular mechanics force field and the resulting structures being minimized with the PM3 semiempirical method. Calculations were performed in the gas phase.
