Positive-ion chemical ionization mass spectra were measured for simple bifunctional aromatic compounds of the type p-XCH,C,H.,CH,Y, where X = NH,, NH(CH,) and N(CH,), and Y = OH and OCH,. For each cornpound, essentially only three peaks of ions, [ MHJ +, [ MH -XHI + and [ MH -YHI +, appeared. The B/
