6-Oxopurine and its analogues form an important class of biological molecules that include
nucleobases and their precursors and are substrates of a wide range of enzymes. Solution …

UV photoelectron spectra of hypoxanthine, xanthine, and caffeine, up to 20 eV, were
calculated and compared with the experimental spectra reported in literature. The …

The vibrational analysis of the two predominant tautomers of hypoxanthine (HX) in solution,
the keto-N1–H/N7–H (HX/N7H) and N1–H/N9–H (HX/N9H) forms, have been carried out by …

In order to advance the knowledge of prototropic tautomerism from the physicochemical
point of view, the purine derivative hypoxanthine has been selected and studied. The overall …

In order to advance in the knowledge of the hypoxanthine physicochemical properties, joint
Quantum Chemical and Monte-Carlo studies of the neutral heterocycle in its N (1)–H/N (7) …

Poly (rI) stabilized by either Na+ or K+ was investigated using uv resonance Raman (UVRR)
spectroscopy. Raman excitation profiles of inosine 5′‐monophosphate demonstrated the …

UV resonance Raman (UVRR) spectroscopy has been used to investigate the three purine
