Dynamic NMR of 1-(methylsulfonyl)-3,5-bis(trifluoromethylsulfonyl)-1,3,5-triazinane reveals the existence of three conformers and two dynamic processes:  ring inversion and rotation about the N−S bond, both processes having ΔG = 13.5 kcal/mol. An unprecedented large reverse Perlin effect (JCHax > JCHeq) was found experimentally and calculated theoretically.
