The 'H and I3C NMR spectra of phenanthro(9,10-b]thiophene were totally assigned using a combination of twodimensional NMR techniques. Direct heteronuclear correlations were established using heteronuclear chemical shift correlation with semi-selective proton decoupling. Two methods were employed to

The total assignment of the 13C and the ' H NMR spectra of four derivatives of 1,3diaza-2,4-diboranaphthalene has been performed. The interpretation of the spectra was achieved from the concerted application of direct and long-range heteronuclear chemical shift correlation and homonuclear COSY two-d
## Abstract ^1^H and ^13^C NMR studies were carried out on benzanthrone and 3β, 4β, 6β, 8β, 9β, 10β and 11βchlorobenzanthrone. Complete assignments of proton and carbon resonances were made with the aid of HHβCOSY, NOESY, CHβCOSY and HMBC techniques. Substitution effects of a chlorine atom are not
## 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
## Abstract The complete assignment of the ^1^H and ^13^C spectra of 2β__exo__β and 2β__endo__βnorβbornenemethanol is presented. Resonance assignment was achieved using ^1^Hβ^1^H double resonance, COSY and ^1^H/^13^C correlation spectra. Computer simulations of the Hβ2 (__exo__ or __endo__) proton
