In both cases, the 7H-keto-amino tautomer was found to be the prevalent form, contrary to aqueous solutions and hydrated polycrystalline guanine, where the 9H-keto-amino tautomer is the most favoured species. This study is a significant contribution for the existing spectroscopic characterisation of this purine base, by unambiguously assigning its vibrational spectra.<\/jats:p>","DOI":"10.3233\/978-1-61499-184-7-127","type":"book-chapter","created":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T15:13:57Z","timestamp":1739978037000},"source":"Crossref","is-referenced-by-count":0,"title":["Guanine &amp;ndash; A combined study using vibrational spectroscopy and theoretical methods"],"prefix":"10.3233","author":[{"family":"Lopes Rui Pedro","sequence":"additional","affiliation":[]},{"family":"Marques M.
