Guanine derivatives were examined using the tandem mass spectrometry (MS/MS) method. Isomeric structure differences were explored by means of the unimolecular decomposition spectra of the common ion m/z 151 having the empirical formula of the guanine molecular ion. An interconversion of the isomeric structures as the sample temperature is gradually raised, was observed.
