主 题:Resonance-enhanced multiphoton ionization Slow electron velocity-map imaging Duschinsky mixing para-Chlorofluorobenzene
摘 要:The geometric structures and vibration frequencies of para-chlorofluorobenzene(p-Cl FPh)in the first excited state of neutral and ground state of cation were investigated by resonanceenhanced multiphoton ionization and slow electron velocity-map *** infrared spectrum of S0 state and absorption spectrum for S1←S0 transition in p-Cl FPh were also *** on the one-color resonant two-photon ionization spectrum and two-color resonant two-photon ionization spectrum,we obtained the adiabatic excited-state energy of p-Cl FPh as 36302±4 cm^-*** the two-color resonant two-photon ionization slow electron velocity-map imagin spectra,the accurate adiabatic ionization potential of p-Cl FPh was extrapolated as 72937±8 cm^-1 via threshold ionization *** addition,FranckCondon simulation was performed to help us confidently ascertain the main vibrational modes in the S1 and D0 ***,the mixing of vibrational modes between S0→S1 and S1→D0 has been analyzed.
