The CD in ion yield for different excitation/ionization schemes for R-(+)-3-methylcyclopentanone was measured with CD laser mass spectrometry (CD-LAMS). The authors discovered a cumulative CD effect of successive electronic transitions, resulting in an enhancement of the CD in ion yield. Two photon excitation of the n-Ï€*-transition compared with the one photon process showed a vanishing CD effect. [on SciFinder(R)]
