| Group IVB metallocene polyamines containing the plant growth hormone kinetin were synthesized employing the interfacial polycondensation system. The products were examined employing two MS techniques. EI MS allows the identification of low mass ion fragments including identification of the linkages that connect the kinetin with the metallocene. It also allows the comparison of fragmentation patterns for known compounds, here the Cp group. While there is some mass overlap, the MALDI MS system allows the identification of higher mass ion fragments to about 180,000 daltons. It also allows the identification, by isotopic abundance comparisons, of ion fragment clusters that contain one and two metal atoms. In general, the two techniques reinforce one another. |
