Abstract The NQR frequencies of chlorines in seven perchloro-compounds were measured at 77°K and above. The assignments of the frequencies were made for each compound. It was found that the resonance frequency is considerably influenced by the electrostatic repulsion between chlorine atoms due to the close Cl···Cl distances. For several compounds, the resonance was found to fade out at rather low temperatures.
