The 'H and uC NMR spectra of tetrahydroquinoxalines condensed with pyridazme, pyrazine, oxazine, oxadiazine, thiadiazine or triazine rings have been measured in DMSO-d, solution. The effects of six-membered heterocycles on 'H and uC chemical shifts and the values of one-bond 'J(CH) and vicinal 3J(HH
