Rezumat:

The EI mass spectra (ms) of dimethylacetal of 3- and 4- nitrobenzophenones have been obtained. The analysis of the experimental spectra evidenced a number of similar fragmentations of these compounds. The new differential techniques of mass spectra establish the nitro group position of the aromatic ring.
