The vib-rotational spectrum of the 2ν_1+ν_5, ν_1+ν_2+3ν_5 and ν_1+ν_3+2ν_4 combination bands of acetylene were measured using a GaAs semiconductor laser at the wavenumber region from 7400 to 7700 cm^<-1> and thc rotational fine structures of the P-, R- and Q-branches were assigned. The formulation describing the spectral line positions by a third order polynomial of J (J+1) with the effective spcctroscopic parameters of ν^<eff>_0, B^<eff>_v, and H^<eff>_v was obtained using sccond order pertubation theory to take the l-type resonance effect into consideration. The spectroscopic constants and the l-type doubling constants were calculated from the effective rotational parameters determined using a least squares fitting procedure for the e-and f-levels.
