IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishN-Alkyl-N-tosyl amino acid esters were ionized by fast atom bombardment (FAB) in a nitrobenzyl alcohol matrix through oxidative processes leading to molecular radical cations (M(+.)). The addition to the matrix of Cu-II salts induces the ionization through proton attachment whereby [M + H](+) are exclusively displayed by the positive-ion FAB spectra. The formation of electron donor-acceptor complexes between the analytes and the matrix lowers the critical energy for the ionization by one-electron removal from the substrates.
