Photodissociation Study of Ca⁺-Dipropylamine Complex

Gas-phase Ca⁺-dipropylamine complex has been subjected to photodissociation (400-690 nm). One reactive product, Ca⁺-NHC₃H₇, is detected only in the region of 450-528 nm, besides the evaporation fragment of Ca⁺, which is dominant throughout the whole spectral region we have studied. The photoreaction channel may be explained in terms of a metal insertion mechanism. The calculated results are in good agreement with the experimental observations.
