reaction dynamics to form d1-diacetylene, DCCCCH (X 1Σ+), and the d1-butadiynyl radical, DCCCC, via the reaction of d1-ethinyl, C2D (X 2Σ+), with acetylene, C2H2 (X1Σg+), are explored in a crossed molecular beam experiment at an average collision energy of 26.1 kJ mol−1. The experiments show that the reaction follows indirect scattering dynamics via a C4H2D intermediate. The calculations confirm that
