The conformational mobility of a series of conjugated dienones is investigated by low-tempera ture NMR-and IR-spectroscopy and interpreted in terms of substituent effects. The stereochemical characterization of conjugated dienones, subject of various spectroscopic studies ' -4 , has to consider the

## Abstract Complete assignments are made for 23 4‐quinolones and related compounds. Literature data are used to calculate chemical shifts for 17 of these compounds: calculated and experimental shifts are in excellent agreement—all within 5 ppm for nine of the compounds and a maximum discrepancy of
13C and 'H NMR parameters were measured for isoproterenol in solution. Spin-lattice relaxation rates were considered and C-H and H-H J couplings were determined. The t rotamer was shown to occur in a much greater abundance than the two g rotamers. Dynamics in solution were interpreted in terms of a
