We present preliminary results of study of middle-resolution optical spectra of Comet 153P/Ikeya–Zhang obtained on May 5, 2002 with the help of the 2.12-m reflector of the Guillermo Haro Astrophysical Observatory. Emission lines of the molecules C₂, C₃, CN, NH₂, CO (Asundi and triplet bands), and H₂O⁺ are identified in these spectra. On the basis of the intensity distribution along the slit of the spectrograph in C₂, C₃, CN emission lines we determined the velocities expansion and life times of these molecules.
