Abstract
Positive ion electrospray ionization mass spectra have been obtained o f deoxyribonucleic acids (DNA) and ribonucleic acids (RNA), including transfer RNAs (77-mer, similar to 25 kDa). For several different solut ion conditions, the charge state distributions of DNA and RNA molecule s were determined. It is postulated that the production of the multipl y charged positive ions results from gas phase dissociation of complex es between nitrogen-containing bases and oligonucleotides.
