title: Infrared photodissociation of non-covalent adducts of electrosprayed nucleotide ions.
abstract: Efficient dissociation of gaseous non-covalent adducts of multiply charged DNA anions can be effected by infrared irradiation to yield minimal dissociation of the DNA molecular ions-far less dissociation than by collisional activation. Examples include removal of adducted impurities from 100-mer DNA anions and removal of all 14 adducted molecules of 1,4-diaminobutane from M(15-) to M(17-) of a 50-mer DNA.
