## Abstract The assignments of the long‐range ^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 long‐range selective ^1^H decoupling with low‐power ^1^H irradiation. Th

## Abstract Long range ^13^C^1^H coupling constants are reported for a number of methylquinoline derivatives. The results have been compared with those observed in the pyridine series and correlated with ^1^H^1^H coupling constants.
Bldg 201-BS-07, Proton and carbon-I 3 assignments based on long-range coupling to the methyl protons are reported for the three isomeric N-methyldiazabenzene salts. All resolved "J,, coupling constants are reported.
The new oxoisoaporphines 7H-dibenzo[de,h]quinolin-7-one, 5-methoxy-7H-dibenzo[de,h]quinolin-7-one, 5methoxy-6-hydroxy-7H-dibenzo[de,h]quinolin-7-one, 5hydroxy-7H-dibenzo[de,h]quinolin-7-one and 5-methoxy-6H-dibenzo[de,h]quinolin-6-one were prepared either by oxidation of their 2,3-dihydro derivative
