Abstract
βConformalβ spectroscopy is a method for the acquisition of accurately localized NMR spectra from noncuboidal regions with optimum signalβtoβnoise ratio, and is based upon the localization of volumes defined by a number of oblique intersecting selected slices. We have previously demonstrated conformal localization of volumes with convex surfaces. In this paper we extend the technique to the localization of concave volumes.

The conformation of diribosylribitol phosphate was studied by means of NMR spectroscopy and molecular dynamics (MD). Starting from 3 J( 1 H, 1 H), 3 J( 31 P, 1 H) and 3 J( 31 P, 13 C) couplings, measured from 1 H NMR, 13 C NMR and COSY spectra, the conformations of the ribose residues and the phosph
