摘要：

We applied the resonant two-photon ionization and mass-analyzed threshold ionization spectroscopic techniques to record the vibronic and cation spectra of m-chloroaniline. The band origin of the first electronic transition was found to be 33658 +/- 2 cm(-1), whereas the adiabatic ionization energy was determined to be 63958 5 cm-1. Within our experimental detection limit, these measured values are the same for both of the Cl-35 and Cl-37 isotopomers. The observed active modes of this molecule in the electronically excited S-1 and cationic ground D-0 states mainly involve the in-plane ring deformation and substituent-sensitive bending vibrations.
