Detection of Nitrogen Metastable Molecules by using the Threshold Ionization Mass Spectrometry.

Abstract

) state has a longer radiation life time and its electron energy is high. Accordingly, it is expected to accelerate chemical reactions in the space where many metastable molecules accumulate. Thus, it is important to detect metastable molecules and to evaluate its number density. The authors used the threshold ionization mass spectrometry to detect N 2 (A increased proportionally to discharge current and its density decreased rapidly in the vicinity of glass wall faced to discharge space.

Threshold ionization mass spectrometry study of singlet molecular oxygen in the deposition of SnO2by PACVD

“…The first part of this work is devoted to a study of oxygen metastable molecules by threshold ionization mass spectrometry (TIMS). Numerous TIMS experiments have been performed by Foner and Hudson [3] on the metastables of N 2 molecules, and more recently by Agarwal et al [4] and Matsuda et al [5]. To our knowledge, only a few authors have used this technique to measure O 2 metastables [6].…”
