Infrared photodissociation of non-covalent adducts of electrosprayed nucleotide ions
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...

| Zusammenfassung: | 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. |
