Mass analyzed threshold ionization (MATI) spectroscopy of trichlorobenzenes via different intermediate vibrational states in the S1 state

Resonant two-photon mass-analyzed threshold ionization of 2,5-difluoroaniline

“…These techniques detect either photons or electrons with high sensitivity. In contrast, the resonance-enhanced multi-photon ionization (RE-MPI) [8,17] and mass-analyzed threshold ionization (MATI) [18][19][20][21] methods can provide the same experimental data with mass information. These techniques are suitable for spectroscopic studies of molecular isomers to avoid spectral congestion caused by presence of impurities, complexes, and clusters in the chemical sample.…”

Two-color resonant two-photon ionization and mass-analyzed threshold ionization spectroscopy of o-chloroanisole

“…These new data provide information about the excitation energy of the S 1 ← S 0 electronic transition (E 1 ) and IE as well as the active vibrations of this molecule in the S 1 and D 0 states. Comparing these data with those of halogen substituted benzene derivatives [16][17][18] allows us to gain knowledge about the isotope and chlorine substitution effects on transition energy and molecular vibration.…”

Mass-analyzed-threshold-ionization (MATI) spectroscopy of 1,2,3-substituted halogenated benzenes via different intermediate vibrational states in the S1 state

“…The MATI spectrum obtained via the S 1 9a 1 mode also shows a breakdown of the Dv ¼ 0 propensity rule. Not the vertical transition into the D 0 9a 1 state is the dominating one, but the band at 242 cm À1 (15 1 ). In addition the 17b mode appears again, also as a combination in 17b 1 9a 1 .…”
