Dynamics of non-rigid molecules. - I. — 13C T 1 NMR study of the reorientational and ring-puckering motions of cyclopentene in the liquid state

Abstract: 2014 Le temps de relaxation spin-réseau T1 et l'effet nucléaire Overhauser des trois carbones distincts du cyclopentène ont été mesurés en RMN du 13C entre 220 et 300 K, afin d'étudier la dynamique d'inversion de cette molécule en phase liquide. Les données ont d'abord été analysées dans l'hypothèse d'une diffusion rotationnelle du cyclopentène considéré comme un rotateur asymétrique rigide. La rotation la plus lente se produirait alors autour du pseudoaxe C5 avec des différences importantes entre les valeurs … Show more

“…Additionally, the ring-puckering motion of liquid CYC was studied by 13 C NMR relaxation. 37 Comparing the exchange rate between its two equivalent bent conformations at different temperatures it was concluded that the activation energy of this process should be rather low. The bent conformation was found to have a puckering angle of 25-301.…”
