Multiphoton ionization mass Spectra of alkyl Iodides at 532 nm
Multiphoton Ionization-Dissociation (MPID) Mass Spectra (MS) of alkyl iodides (including methyl iodide, ethyl iodide, n-propyl iodide and i-propyl iodide) are obtained using a time-of-flight mass spectrometer at 532 nm. It is found that all kinds of parent molecules are first two-photon resonantly excited to A-band. CH3I molecule is resonantly exited to 1A(2) state of A-band, and its MPID belongs to parent-ion ladder mechanism. However other molecules are resonantly exited to A-band and then go through dissociation. Fragment ions are produced by ionization and dissociation of neutral fragments, Their MPID belongs to neutral-fragment photoionization mechanism. Moreover, the dissociation pathways of isopropyl cation are discussed through branching ratio analyses.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 450412-29-0 is helpful to your research. Recommanded Product: 450412-29-0.
