IR spectrum of jet-cooled clusters of guanine and cytosine has been recorded in the 500-1800 cm-1 range by ion-dip spectroscopy. Some 30 clearly separated and sharp resonances are observed. The combination of the experimental data with new high-level ab initio calculations shows the preference of enol form of cytosine in the pair
IČ spektrum klastru guaninu a cytosinu bylo změřeno v rozsahu 500-1800 cm-1. Bylo nalezeno okolo 30 jasně ohraničených rezonancí. Teoretické i experimentální spektar naznačují přítomnost enolické formy cytosinu
