We report a large scale configuration interaction calculation of Cl V by taking account of relativistic effect through the Breit-Pauli approximation. Excitation energies of the lowest 49 fine structure levels relative to the ground state \(3s^23p(^2{\rm P}^o_{1/2})\) are found to be in good agreement with the NIST recommended data. Oscillator strengths, line strengths and radiative rates for the optically allowed and intercombination transitions among these levels and life times for some relatively longer lived fine structure levels are also reported for this ion. We confirm the interesting result that the life times for the multiplets of \(3s3p^2(^4{\rm P})\) and \(3s3p(^3{\rm P})3d(^4{\rm F})\) are of the order of microseconds.
