In this paper we show that the stacked structures of 9-methyl adenine...adenine are comparably stabe as the most stable hydrogen bonded structures and that the calculated IR pattern of the stacked structures is in a very good agreement with the experimental spectrum. The pair 7-methyl adenine...adenine on the other hand shows a nearly planar hydrogen bond arrangement and no stacked structure was observed
V této práci je ukázáno, že patrové a planární struktury páru bazí 9-methyl adenin...adenin jsou přibližně stejně stabilní a vypočtené IČ spektrum patrové struktury odpovídá experimentálně nalezenému spektru. Naopak v páru 7-methyl adenin...adenin byla nalezena pouze planární struktura
