Abstract

The tautomeric composition of isolated adenine has been analyzed using computational IR spectroscopy. A comparison with experimental data has demonstrated that, in addition to adenine-N9H, which dominates in the quantitative content, two more tautomers that have the N9H imino and N7H amino forms exist in the isolated state and in the gas phase.
