Characterization of trisubstituted aromatic isomers and structural identification by spectroscopic methods. I- Identification using GC-MS

The mass spectra of 5 trisubstituted aromatic compounds were studied. The spectra were recorded by local GC-MS at 70 eV and compared with bibliographic spectra. The spectra of each compound were different. The using of local GC-MS for identification required recording the spectra references at the same conditions.
