چکیده انگلیسی
Theoretical calculations predicted that there are only two stable conformers, trans and cis, for 2-fluoro-N-methylaniline (2FNMA) in the S0, S1 and D0 states. Compared to the cis conformer, the trans one is more stable, and has a population more than 99% at room temperature. The optimized molecular skeleton of trans and cis 2FNMA are both non-planar in the S0 state, but planar in the S1 and D0 states. The one-dimensional potential energy surface of 2FNMA in the S0 state is obtained. The Resonance-enhanced two-photon ionization (R2PI) and Mass-analyzed threshold ionization (MATI) spectra of trans 2FNMA are obtained. The first electronic excitation energy (E1) and the adiabatic ionization energy (IE) of trans 2FNMA are determined. The substitution effect on the molecular structures, transition energies and vibrations of 2FNMA are discussed.
