Reactions of NH(a 1Δ) with propane in the gas phase

Reactions of electronically excited NH(a ¹Δ) with propane have been investigated in the gas phase at room temperature. Pressure dependence of the yields of insertion and fragmentation products was measured. The relative secondary/primary CH bond reactivities (per bond) are determined to be 1.5 for insertion and 7.5 for abstraction.
