Vacuum UV photolysis of CO2. Rare-gas oxide formation in matrices

Electron impact dissociation of N2O and CO2 with single particle detection of O(1D2)

“…The Ne matrix was identified in the earlier work [13,15,21,22] as being different from the other rare gas matrices in that the spin forbidden ( 1 D -3 P) emission was also observed following VUV photon irradiation of matrices containing traces of O2, N2O or CO2. More recently, Belov et al [23], used 2 keV electron bombardment of Ne crystals containing a trace of O2 and confirmed that the ( 1 D -3 P) emission was observed from the matrix.…”

Photochemical reactions involving matrix-isolated atoms

“…Thus 8.4-eV photolysis of C02 in Ar leads to emission from CO(a37r) (gas threshold 11.45 eV) and O0S) (gas threshold 9.64 eV). 83,88 The mechanism of this sensitization is thought to involve a complex between the rare gas (Ar or Kr but not Ne) and 0(1D). This complex has a lifetime long enough for a second photon to be Oxygen-atom transfer from N20 or from C02 to coordinated CO can also be effected using 314-nm photons via absorption by W(CO)6.90 Similarly, photolysis of W(CO)6 in 02 doped N2 matrices yields, inter alia, N20.…”

Detection of Metastable Atoms and Molecules using Rare Gas Matrices

“…In 1948, Vegard and Kvifte realized that green line emission, observed when a small oxygen impurity was present in a solid N 2 : Ar mixture, was due to the O( 1 S-1 D) transition. There have been many examples of this matrix isolation spectroscopy using both electron and photon bombardment (e.g., Belov and Yurtaeva, 2001;Belov et al, 2000;Fournier et al, 1982;Girardet et al, 1986;Goodman et al, 1977;Lawrence and Apkarian, 1992;Maillard et al, 1982Maillard et al, , 1983Taylor et al, 1981;Walker et al, 1981). Yurtaeva et al (1990) obtained similar results.…”
