N. Watanabe et al., REACTIONS OF CARBON CLUSTER IONS STORED IN AN RF TRAP, Zeitschrift fur Physik. D, Atoms, molecules and clusters, 26, 1993, pp. 252-254
Reactions of carbon cluster ions with O2 were studied by using an RF i
on trap in which cluster ions of specific size produced by laser ablat
ion could be stored selectively. Reaction rate constants for positive
and negative carbon cluster ions were estimated. In the case of the po
sitive cluster ions, these were consistent with the previous experimen
tal results using FTMS. Negative carbon cluster ions C(n)- (n=4-8) wer
e much less reactive than positive cluster ions. The C(n)O- products w
ere seen only in n=4 and 6.
