Laser-induced fluorescence excitation spectrum of oxalyl cholride (C2O2Cl2) in the rang of 358-372.5nm has been observed. More than 60 vibrational transitions have been assigned, in which 24 bands were not found in absorption spectrum. From the vibrational structure, we obtained some of the vibrational frequencies in ground state and excited state in which v7=84cm-1 and v7= 164cm-1 are new data. The rotational analysis of high resolved 401 band leads to the rotational constants A = 0.190cm-1, B = 0.114cm-1, and C = 0.048cm-1.
