A reexamination of the vibrational–vibrational energy transfer from N2(v) to NO+.

We have reexamined whether N2(v=1) transfers its vibrational quantum to NO+(v=0). In light of recent results that show that CH3I does not charge transfer rapidly with NO+(v=1), we show that previous measurements could not have detected vibrational–vibrational (V–V) energy transfer from N2(v=1) to NO+(v=0). We have made measurements to examine this process by using C2H5I as the monitor for NO+(v=1). Our results show that NO+(v>=0) is indeed produced from reaction of NO+(v=0) with N2(v) but these results cannot be used to distinguish between resonant V–V energy transfer from N2(v=1) to NO+(v=0) and V–V, T energy transfer from higher levels of N2(v).
