The 'H NMR spectra of variously annulated pyranocoumarins are reported. The complete assignment of chemical shifts was achieved by using coupling constants and the shift effects induced by the introduction of methyl groups at various positions on the pyranocoumarin nucleus, and by comparison with th

β¦ Synopsis
An analysis of the 'H NMR spectra of polyhydroxycarboxylates is presented. Conclusions with regard to the configuration and the conformation are drawn from chemical shifts and vicinal coupling constants.

## Abstract The ^1^H NMR spectra of 26 nitrated aminopyridines were measured and interpreted. Chemical shift assignments were based on existing chemical shift rules for substituted pyridines and spectral comparison with compounds of similar structure. Some __o__βaminonitropyridines were found to gi
## Abstract The ^1^H NMR Spectra of 28 substituted phenazines have been measured and analysed with computer assistance. Substituent increments of chemical shifts were calculated for methoxy, carbomethoxy and methyl derivatives. The influence of these substituents on coupling constants has been exam
