Abstract
Cyanodiacetylene, H(C ≡ C)2 CN has been produced by a radiofrequency discharge in a mixture of acetylene, HCCH, and hydrogen cyanide, HCN. This reaction is of astrophysical importance, since it lends support to the possibility of the ion-molecule formation scheme of producing long carbon chain molecules in interstellar sources. From a measurement of the J = 4←3 transition of HC5N the nuclear quadrupole coupling constant eqQ = - 4.242 (30) MHz was determined.
