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

-13 NMR Spectra of lsocoumarin, N-Methyl-l(2H)-isoquinolinone and Related Compounds The 13C NMR spectra of isocoumarin, Kmethyl-I (PH)-isoquinolinone and 14 of their 3and/or 4-substituted derivatives were measured and assigned with the aid of various spectral techniques. The values of the one-bond and some of the long-range 13C-lH coupling constants are reported. The effect of substitution on the 13C chemical shifts is discussed.
