The vinyl radical in the ground vibronic state produced in a supersonic jet expansion by 193 nm excimer laser photolysis of vinyl bromide is discussed. The millimeter-wave spectroscopic technique is used for the investigation purpose. The ground state is split into two components, due to the proton tunneling, of which the lower and higher ones are denoted as 0+ and 0- respectively. Eight pure rotational transitions are observed for each of the 0+ and 0- states in the frequency region of 60-250 GHz.
