The complete assignment of the 'H and 13C NMR spectra of two carbothioamide-substituted meroterpenes is presented. Resonance assignments were achieved by the use of one-and two-dimensional NMR, NOED, selective decoupling measurements and the deuterium isotope effect on the I3C chemical shifts. Six-m

## Abstract The ^1^H and ^13^C NMR spectra of ‘Thiele's ester,’ i.e. dimethyl 3α 4α, 7α, 7α‐tetrahydro‐4,7‐methano‐1H‐indene‐2,6‐dicarboxylate, have been assigned completely by using a combination of one‐ and two‐dimensional NMR techniques. The results thereby obtained afford the first unambiguous
## Abstract ^1^H and ^13^C NMR studies were carried out on benzanthrone and 3‐, 4‐, 6‐, 8‐, 9‐, 10‐ and 11‐chlorobenzanthrone. Complete assignments of proton and carbon resonances were made with the aid of HH‐COSY, NOESY, CH‐COSY and HMBC techniques. Substitution effects of a chlorine atom are not
Using two-dimensional heteronuclear 'H-13C chemical shift correlation spectroscopy via one-bond and long-range couplings, all 13C resonances of bilirubinl X a and its dimethyl ester in dimethyl sulphoxide solution are assigned, independently from reference to partial structures. Previous ambiguities
