Abstract
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.
