title: Gas-phase isolation of diethyl guanosine 5'-monophosphate and its conformational assignment.
abstract: We show that intact neutral molecules of guanosine 5'-monophosphate can be vaporized by laser desorption when its phosphate group is esterified. The UV and IR spectroscopic measurements of this nucleotide reveal the existence of a novel internal hydrogen-bonding conformation of the phosphate group and guanine moiety.
