Abstract

The microwave spectrum of the nucleic acid base adenine in a cw seeded supersonic beam has been analyzed indicating that the amino, N (9) H tautomer is the most stable in an isolated environment. A comparison of the experimental rotational constants is made with those obtained using ab initio 3-21G basis SCF calculations for three of the lower- energy tautomers.
