## 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

NMR spectra of all-trans retinal, and vitamin A, were measured by the pulse Fourier transform method in CCI,. All peaks in these spectra were assigned from considerations of chemical shifts, half proton-decoupled spectra, spin-lattice relaxation times and induced chemical shift by the addition of sh
