摘要:

Photoelectron spectra of three natural methylated xanthines are discussed by qualitative considerations on the constitutive subunits and the methylation effects. The first band in all three cases can be assigned to enaminic molecular subunit, as in uracil; also the positions of the lone pairs of nitrogen and oxygen atoms are discussed.
