Abstract
The conformational preferences of nicotine in three protonation states and in the gas phase as well as aqueous solution are investigated using several computational procedures. Conformational aspects emphasized are N-methyl stereochemistry, relative rotation of the pyridine and pyrrolidine rings, and pyrrolidine ring conformation. All methods consistently predicted that the N-methyl trans species are most stable for all protonation states in both gas phase and in water. However, the cis/trans energy gap is significantly reduced in water. Additionally, the two pyridine ring rotamers, which are energetically equivalent in the gas phase, experience different solvation energies in water.
