title: Comment on 'new infrared spectra and tautomeric studies of purine and alpha L-alanine with an innovative sampling technique.'.
abstract: IR spectra claimed [Spectrochim. Acta A 55 (1999) 2329] to be those of NH2CHMeCO2H and N(7)H purine, as isolated molecules in KBr. are those of cationic species formed in the acid media used.
