A computer-assisted method of conformational analysis for porphyrin molecules bearing tlexiile side-chains has been developed. The method utilizes the ring current-induced chemical shift changes of the side-chain protons which arise from the porphyrin mauocyde and any attached aryl rings. The treatm

β¦ Synopsis
The computer-assisted analysis data of the 'H NMR spectra of peracetylated aand 8-1-3-and -1-4-linked o-galactopyranosyl-0-galactopyranoses and several tetraacetylated-0-methyl derivatives of o-galactopyranose are reported.

The rare alkaloid casimiroedine and its peracetylated derivative both show complex 1 H and 13 C spectra with almost all signals doubled owing to slow rotation about the amide bond. Nevertheless, it is possible, using 2D NMR methods, to assign fully the 1 H and 13 C spectra of the major and minor con
## Abstract A series of nine diethyl phosphonates were prepared and an analysis of their ^1^H NMR spectra was undertaken. Some erroneous literature assignments of signals were revised.
