Experimental determination of pseudorotation potentials for disubstitutedcyclopentanes based on spin-spin coupling constants

Abstract

Complete analysis of 1H-NMR spectra of trans-1,2- dichlorocyclopentane and trans-1,2-dibromocyclopentane was performed with use of our total lineshape fitting algorithm VALISA. The resulting high precision spin-spin coupling constants were then applied to the problem of conformational analysis, yielding a continuos potential of pseudorotation for the studied compounds in CDCl3, CCl4, and CD3CN solutions.
