## Abstract Recent developments in dynamic nuclear polarisation now allow significant enhancements to be generated in the cryo solid state and transferred to the liquid state for detection at high resolution. We demonstrate that the Ardenkjaer–Larsen method can be extended by taking advantage of th

## Abstract The ^13^C n.m.r. spectrum of benzofuroxan at −15°C is assigned on the basis of selective decoupling experiments and by comparison with the ^13^C chemical shifts of model compounds. The ^13^C spectra were also measured in trifluoroacetic acid as a solvent. From the temperature dependence
Carbon, nitrogen and oxygen NMR spectra of some nitro derivatives of pyrrole and imidazole have been investigated. The 13C chemical shifts of para-carbons and the 170 chemical shifts of the nitro group correlate qualitatively with the electron densities on these carbon and oxygen atoms, which in tur
