Web10 mei 2011 · For less polar compounds, a more complicated procedure called reactive DESI has been shown to be more practical [ 5 ]. Recently, a more efficient ionization method using a nebulized spray of ionized toluene for compounds of low proton affinity and low acidity, such as cholesterol, has been described [ 6 ]. WebHere we present a multimodal investigation of the strong-field induced ionization, isomerization and fragmentation of toluene. The toluene molecules are ionized with a femtosecond laser pulse, and the ionic products are measured using momentum-resolved coincidence ion time-of-flight mass spectrometry (TOF- MS) and gas-phase UED.
