We obtained the CN(ΔV=0 ΔV=0 ) and C2(ΔV=0,±1 C2(ΔV=0,±1 ) spectra of comet Hale-Bopp(C/1995 O1) at the Kyunghee Observatory and Bohyunsan Astronomical Observatory between March 7 and May 12, 1997 The fluxes for each molecular band were measured and then the production rates and column densities of CN and C2 C2 were calculated using a simple model. The resultantproduction rates of CN and C2 C2 are logQ(CN)=27.4 at r=0.94 AU(preperihelion) and logQ(C2)=27.3 logQ(C2)=27.3 at r=0.94 AU(postperihelion), respectively.
