摘要

Abstract The behaviour towards low collision energy processes (eV range) of [M [BOND] H]− prepared under negative ion chemical ionization (NICI) ammonia conditions from 17β- estradiol-17-fatty acid esters has been investigated. From such bifunctional compounds containing two acidic sites (ie phenol and ester groups), two isomeric forms (ie phenoxide and enolate forms) characterize the [M [BOND] H]− ion structures, whose distribution ...
