The complete assignment of the carbon NMR spectra for 14 N-arylphthalisoimides was achieved using the concerted application of one-and two-dimensional NMR techniques. The parameters previously reported in the literature were found to be wrong.

✦ Synopsis
coupling constants are reported. The stereochemistry (E and Z) of a series of new acyclic ˇ-phosphonylated hydrazones was assigned on the basis of the chemical shifts of carbons in ˛(C-1) and ˛0 (C-3) positions with respect to the C N moiety.

1 H and 13 C NMR spectral data for phytochelatin, NH 3 C --Glu-Cys 2 -Gly-COO , were assigned by a combination of one-( 1 H, 13 C) and two-dimensional (DQF-COSY, CH-COSY, HMBC) NMR experiments.
The indole alkaloid strychnobrasiline was studied using one-and two-dimensional NMR techniques. The interpretation of these spectra led to the complete assignments of all carbon and proton chemical shifts.
The 13C NMR spectra of several 1-(2-hydroxymethylcyclopentyl)and 1-(2-hydroxymethylcyclopentylmethyl)uracils and 5halouracils (X ¼ Cl, Br or I) were fully assigned with the aid of one-(13C, 1H-1H NOE, DEPT) and two-dimensional (HMQC) NMR experiments.
The 1 H and 13 C NMR resonances of 12 tetracyclic phenothiazine derivatives were completely and unequivocally assigned by the concerted application of 1 H-detected heteronuclear one-bond (gs-HMQC) and long-range (gs-HMBC) gradient selected correlation experiments. 1 H and 13 C chemical shifts are al
The 13 C, 31 P and 1 H NMR spectra of a series of dioxaphosphinopyridines and pyridoazaphosphinines were studied. The interpretation of the chemical shifts of these compounds was based on model compounds and on selective irradiation and two-dimensional shift correlated NMR techniques.
