Abstract
The assignment of the ^13^C and ^1^H resonances of phenanthrenes and stilbenes di‐substituted with oxygenated side‐chains is presented based on chemical shifts, multiplicities and proton‐selective irradiation.

The complete assignment of the 1H and 13C NMR spectra of eight thienyl-substituted chromenes was achieved by the concerted application of homonuclear (gs-COSY), 1H-detected heteronuclear one-bond (gs-HMQC) and long-range (gs-HMBC) gradientselected correlation experiments.
## Abstract A series of ten (__E__)‐stilben‐4‐ols, HOPhCHCHPhX, with X = H, 4′‐Cl, 4′‐F, 4′‐Me, 4′;‐OMe, 3′‐Me, 3′‐OMe, 3′‐OH, 3′‐F and 3′,4‐diOMe, were studied using one‐ and two‐dimensional NMR techniques. Interpretation of these spectra led to definitive assignments of all carbon and hydrogen c
## Abstract ^1^H, ^13^C and ^15^N NMR chemical shifts of 10 substituted pyrazolo[1,5‐__a__]pyrimidines were assigned based on DQF ^1^H, ^1^H COSY, PFG ^1^H, ^13^C HMQC and PFG ^1^H,X (X = ^13^C and ^15^N) HMBC experiments and on literature data. Copyright © 2002 John Wiley & Sons, Ltd.
