Mass-analyzed threshold ionization (MATI) spectroscopy in a conventional time-of-flight mass spectrometer

High Rydberg states of DABCO: Spectroscopy, ionization potential, and comparison with mass analyzed threshold ionization

“…2,27,[31][32][33][34] Here the experimental difference between the ''integrated doubleresonance'' measurements and the MATI measurements is the application in the latter case of a small electric bias field in the extraction region, and a high voltage on an ion reflector in front of the detector. The bias field ͑between 0.5 and 4 V/cm͒ is present either before or shortly ͑Ͻ100 ns͒ after the excitation laser pulse arrives.…”

Electric Field Induced Dissociation of Molecules in Rydberg-like Highly Vibrationally Excited Ion-Pair States

“…For this reason, the spectrometer was translatable along the molecular beam axis (under vacuum). The spectrometer geometry is similar to that used for MAT1 by Jouvet and CO-workers [94].…”

A high-resolution vacuum ultraviolet photoionization, photoelectron, and pulsed field ionization study of CS2 near the CS2+(X 2Π3/2,1/2) thresholds

“…12 It has been shown that a synchrotron radiation source, when operated in a few bunch mode, can also be used for PFI-PE studies. 21,22 Recently, methods have also been introduced for the measurements of mass analyzed threshold ions ͑MATI͒ formed in the Stark field ionization of high-n Rydberg species prepared by excitation using VUV laser [23][24][25][26][27] or cw synchrotron radiation. 10 The advancement of the PFI-PE and MATI techniques are the most exciting developments in the field of VUV photoionization-photoelectron spectroscopy.…”
