Indication of the molecular ion was made using universal
analytical technique – mass spectrometry (MS),
specifically MALDI-TOF MS (mass spectroscopy of laser desorption
ionization in the matrix) on the mass spectrometer
Biflex type III (BRUKER). This technique is based on
the ionization of molecules and subsequent detection of
ions in the electrolyte as a function of their mass-to-charge
ratio (m/z) [17]. As a matrix, α-cyano hydroxycinnamone
acid (CCA) was used. As a result of the mass spectrometry,
mass specters were obtained.
