The Ionization Potential of Si2N and Si2O

“…This means that the nonresonant ionization potential results obtained here were, within our limits of resolution, unaffected by the electric field. This result is in agreement with previous studies . Very similar results as a function of excimer photon energy and photon flux are obtained when NO 2 is seeded into an Si x /He supersonic expansion, suggesting that the nitrogen source eminates from the complete dissociation of NO 2 .…”

“…With an accelerating field of 394 V/cm, the appearance potential is lowered from the true IP of the molecule in question by approximately 121.5 cm -1 , or about 0.015 eV . This means that the nonresonant ionization potential results obtained here were, within our limits of resolution, unaffected by the electric field.…”

“…The resulting molecular beam was skimmed by a 4 mm diameter skimmer as it passed into a time-of-flight chamber. The time-of-flight mass spectrometer employed for these studies has been described previously …”

Spectroscopy of silver dimers in triplet states

“…Here, we will concentrate on the photoemission from Ag 2 . From the gas phase, the ionization potential (IP) is known to be 7.66 eV [15]. The R2PI of the dimer inside the helium droplets was first performed by Federmann et al [9], and absorption above 3.8 eV was assigned to transitions into high vibrational levels of the first excited singlet state A 1 + u ← X 1 + g .…”
