✦ Synopsis

The 13C NMR chemical shifts, one-bond and some long-range l3C-'H coupling constants and the 'H NMR chemical shifts for isoquinolinone, phthalazinone, quinazolinone and their derivatives containing CH, COOH, COOCH, and CH,COOH substituents in the hetero-ring are reported. The NMR data are in agreement with the lactam structure for all compounds studied; no evidence for the detectable presence of other tautomers was obtained.
