Abstract:
Spectrophotometric observations of the coma of the comets C/2000 WM 1 (LINEAR) and C/2002 C1 (Ikeya-Zhang) were taken during Now, Dec 2001 and Mar, Apr 2002 respectively with 104-cm telescope of the State Observatory, Nainitalm CN (λ 4695, λ 5165 and λ 5538 Å)and C₂ swan band ( λ 4695, λ5165 and λ 5538)have been identified in both the comets. Na I emission was detected in comet Ikeya-Zhang. An estimate of CN and C₂ abundances and their production rates have been derived. Dust production rates have also been determined.
