英文摘要 | With the deep development of environmental investigation, some alkyl bromides of higher homolog(e. g., C2H5Br, n-C3H7Br, n-C4Hg9Br) in the lower stratosphere have attracted a little attention in recent years. But the photodissociation dynamics of them have not been studied. In this work, we reported the photodissociation dynamics of n-alkyl bromides R-Br (R = n-alkyl radical) (C2H5Br, n-C3H7Br, n-C4H9Br) at 234 and 267 nm using resonace-enhanced multiphoton ionization (REMPI) with time-flight mass spectrometry (TOF-MS) and the goal was to study the dependencies of the relative quantum yields of phi(Br*) and phi(Br) on photon energy and the molecular complexity. The measured values of the phi(Br *) were found to be phi(Br*)(234nm) = 0.286 and (Br*)(267nm) = 0.338 for C2H5Br, phi(Br*)(234nm) = 0.356 and phi(Br*)(267nm) =0.294 for n-C3H7Br, phi(Br*)(234nm) = 0.428 and phi(Br*)(267nm) = 0.341 for n-C4H9Br. The results of phi(Br *) clearly showed an increasing tendency with the increase of molecular complexity at 234 nm (C2H5Br |
