The benzonitrile dimer is an interesting example for a homo dimer. The rotationally resolved UV spectra of the electronic origin of the benzonitrile dimer has been measured. The benzonitrile dimer was found to be of C2h symmetry in the S0 and S1 state. From the inertial parameters, the N..H-distance was found to be 236 pm in the electronic ground state and 232 pm in the electronic excited state.
