We present resonant two-photon ionization and IR–UV double resonance spectra of methylated xanthine derivatives including 7-methylxanthine dimer and theobromine dimer seeded in a supersonic jet by laser desorption. For 7-methylxanthine, theophylline and theobromine monomer we assign the lowest energy tautomer based on comparison with IR–UV double resonance spectra and calculated IR frequencies.

Jsou ukázány dvoufotonová ionizační a IR-UV dvouresonanční spektra derivátu metylovaného xantinu včetně dimeru 7-metylxantinu a theobrominu. Pro studované monomery jsou nalezeny tautomery s nejnižší energií.
