Abstract: 14 potential functions V(φ) of the internal rotations around the C – C bonds in molecules of 1,1,1-trifluorine alkanes CF3 – (CH2)n – CH3, where 1 ≤ n ≤ 4, were obtained and approximated by Fourier series. The local minima of V(φ) and transition states (TS) have been studied for all examined compounds. A comparison of the rotation characteristics of studied molecules those of same in n-alkanes and 1-monofluorine alkanes was performed. The transferability of rotation parameters around C – C bonds has been showed.
Keywords: 1,1,1-trifluorine alkanes, potential function, conformational analysis, internal rotation.
