Tritium NMR in conformational analysis: isotopic perturbation of the ring inversion equilibrium in [3H]cyclohexane
Abstract
Integration of the axial and equatorial tritium signals in the 3H NMR spectrum of [3H]cyclohexane at –88°C shows that tritium prefers the equatorial site by 11.2 ± 0.5 cal mol–1(1 cal = 4.184 J), in agreement with expectations based on previous NMR work with [2H]cyclohexane.
