Abstract:
The photoionization and photodissociation of bromoethane have been studied by using synchrotron radiation. The photoionization efficiency (PIE) curves of some fragments ions are measured. Based on these curves, the ionization potential of C2H5Br is determined to be 10.29eV,and the appearance potentials of C2H5 + ,CH2Br +are measured to be 10.60eV, 13.2eV respectively. We also have performed G2MP2 calculation on these fragments. According to experimental result and G2MP2 energy, the enthalpy of formation of ions C 2H 5 +,CH 2Br +,C 2H 5Br +,the bond energy of D 0(C 2H 5 +-Br),D 0(-Br),D 0(CH 2Br +-CH 3) have been evaluated. The most possible channels of the dissociation photoionization have been analyzed.
