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 (Δv = 0) at 3888 Å, CH+C₃ at 4050 Å and C₂ (Δv = +1, 0, -1) at 4690 Å, 5160 Å and 5530 Å respectively, were identified. Column densities and production rates have been determined.
