Description	Spektroskopické vlastnosti páru bazí guanin-cytosin byly studovány pomocí experimentálních (IČ a UV spektroskopie) a teoretických (přesné korelované kvantově-chemické výpočty) metod. Watson-Crickovská struktura tohoto páru bází vykazuje narozdíl od ostatních struktur tohoto páru širokou specifickou UV absorbci, která může být vysvětlena velmi rychlou vnitřní konverzí. (cs) To investigate the role of UV irradiation in base-pairing we have studied guanine (G) and cytosine(C) base pairs. We distinguished base-pair structures by IR-UV hole-burning spectroscopy as well as by high-level correlated ab initio calculations. The Watson-Crick structure exhibits broad UV absorption, in stark contrast to other GC structures and other base-pair structures. This broad absorption may be explained by a rapid internal conversion that makes this specific base pair arrangement uniquely photochemically stable.
