Abstract
Using five high-resolution spectra of comet C/2000 WM1 (LINEAR) obtained on December 1 and 2, 2001 (UT) with the fiber fed extended range optical spectrograph (FEROS) installed on the 1.52-m reflector of the ESO (Chile, La Silla), we have constructed a high spectral resolution atlas and catalogue of cometary emission lines of this comet. Many emission lines of the molecules C2, C3, CN, CH, CH+, NH2, CO+, H2O+, and presumably CO and C2â were identified in the spectral range λλ 4000-9000 Ã
in the comet spectra. The total number of identified emission lines is 4537: C2 - 2734, NH2 - 1195, CN - 289, C3 - 158, CO - 60, H2O+ - 51, CH - 50, CO+ - 16, CH+ - 8, C2â - 5. Also there are many unidentified emission lines in the comet spectrum.
