Wh. Jones et Ig. Csizmadia, POLYMERIC (NO)(3)(N(2)O)N, (NO)(3)(N(2)O)N(-) - AN INTERPRETATION OF EXPERIMENTAL-OBSERVATIONS(), AND (NO)(3)(N(2)O)N(), Zeitschrift fur Physik. D, Atoms, molecules and clusters, 32(1-2), 1994, pp. 145-152
Semi-empirical and ab initio calculations are reported which provide a
possible explanation for reported experimental results on 2-photon io
nization of NO containing a few percent of N2O, which found (NO)3(N2O)
n+or- clusters to be significantly more abundant than other (NO)m(N2O)
n products. It is found that the observed abundances of (NO)3(N2O)n io
nic clusters may be accounted for by the existence of covalent cyclic
trimers of nitric oxide attached to oligomers of nitrous oxide. The ex
tra stability of NO trimers in the observed clusters appears to arise
from (NO)3+ rather than (NO)3. Attachment of an (N2O)n side chain to (
NO)3+ occurs exothermically. It is suggested that the addition of N2O
to cyclic-(NO)3+ might provide a means of making a polymer of nitrous
oxide, which could have useful properties.
