[摘要]：In order to improve the understanding of the interactions of arom. s,s-biradicals with DNA, the reactivity of three isomeric s,s-biradicals toward four dinucleoside phosphates was studied in a mass spectrometer. The dinucleoside phosphates were evapd. into the mass spectrometer by using laser-induced acoustic desorption (LIAD). The results demonstrate that the structure of the s,s-biradical and the base sequence of the dinucleoside phosphate can have a major influence on these reactions.
