The Relativistic Quantum Defect Orbital (RQDO) method without and with explicit inclusion of core polarization has been applied to the study of oscillator strengths of fine structure transitions in neutral chlorine, some of which are important in interstellar chemistry. The resulting oscillator strengths are analyzed in terms of other theoretical results and some available experimental data. For the 3p4(3P)4f - 3p4(3P)5g lines we supply the only available results at the moment.
