Abstract
The ^13^C NMR spectra of chloroquine and related 4βaminoquinolines have been completely assigned by the use of ^1^Hβ^13^C correlation sequences based on direct and longβrange J(CH) coupling constants in conjunction with DEPT.

## One-bond and long-range two-dimensional 'H-I'C NMR experiments allow the unequivocal assignment of 13C and 'H spectra. On this basis, previous assignments of 13C signals of grossularine-1 and -2 have been revised.

## Abstract The assignments of the longβrange ^13^C, ^1^H coupling constants in the ^13^C NMR spectra of the base moieties of several purine and pyrimidine nucleosides and their analogues were established by the application of longβrange selective ^1^H decoupling with lowβpower ^1^H irradiation. Th
## Abstract The ^1^H NMR spectrum of naphtho [1β²,2β²:4,5]thieno[2,3β__c__]quinoline is highly congested because all the protons are in an aromatic environment, and the structure of the molecule is nearly symmetric. With this in mind, the assignment of the ^1^H and ^13^C NMR spectra of this compound
