Abstract
Spectrophotometric observations of the periodic comet P/Swift-Tuttle (1992t) were taken through 104 cm telescope of Uttar Pradesh State Observatory Nainital, using EG & G spectrograph coupled with optical multichannel analyser and reticon array detector in the optical region of the spectrum, during four nights of December 1992. The molecular emission bands of CN (Δν = 0) at 3888 Å, CH + C3 at 4050 Å and C2 (Δν = +1,0, −1) at 4690 A, 5160 Å and 5530 Å respectively, were identified. Column densities and production rates have been determined.
