N.M.R. studies of aldonolactones. The 80-MHz proton N.M.R. and 20-MHz proton-coupled 13C N.M.R. of D-Arabinono-1,4-lactone in D2O solutions

Abstract

The 80-MHz proton n.m.r. spectrum of D-arabinono-1,4-lactone in D2O has been simulated and the results utilized in the assignment of the 20-MHz proton-coupled 13C n.m.r. spectrum. Two-and three-bond carbon-proton coupling constants have been derived from computer simulations and are discussed in terms of the dihedral angles in the preferred conformation.
