The bilateral symmetric structure of glycerol affords a set of nine different conformers due to free rotation around each of the glycerol sn-1,2 and sn-2,3 C-C bonds. (In the current study, the three rotamers (α, γ, and β) are denoted also with gt (gauche-trans), gg (gauche-gauche), and tg (trans-gauche) rotamers).
