Rezumat:

The splitting in the electrospray ionization spectrometer of several azulene substituted six-membered heterocycles (pyranylium salts, pyridinium salts, and pyridine) was analyzed and some features of fragmentation were evidenced. The splitting fragments were found to be similar for all heterocycles. The alkyl groups substituted at azulene moiety are broken at the same time with the heterocyclies decomposition. The N+-substituents in pyridinium salts are however lost before other system transformations occur.
