The laser-induced fluorescence (LIF) spectra for C<SUB>2</SUB> Swan system (d<SUP>3</SUP><I>&pi;</I><SUB>g</SUB>-a<SUB>3</SUB><I>&pi;</I><SUB>u</SUB>) were observed with an Ar<SUP>+</SUP> laser. Two laser lines of 472.7 and 514.5nm coincided with two ro-vibronic transitions: <I>R</I>(4) (<I>&Omega;</I>=2-2, =1-0) and <I>Q</I>(21) (<I>&Omega;</I>=2-2, <I>v</I>=0-0). The analysis yielded the vibrational parameters for the a<SUP>3</SUP><I>&pi;</I><SUB>u</SUB> electronic state. The observed LIF spectra could not be explained using the known parameters for the d<SUP>3</SUP><I>&pi;</I><SUB>g</SUB> electronic state. The parameters for the d<SUP>3</SUP><I>&pi;</I><SUB>g</SUB> state were redetermined through the reanalysis of the emission spectra for C<SUB>2</SUB> Swan system. The obtained parameters well explained the LIF spectra.
