The observations and research of the short-period comet 8P/Tuttle by optical spectra with an average resolution (λ/Δλ ≈ 1500) are presented. The spectra were obtained in January 2008 on the mountain observatory «Peak Теrskоl» (Russia, the North Caucasus) with the help of reflecting telescope Zeiss-2000 (D = 2.0 m; F2 = 16 m). On the basis of obtained spectral material was carried the identification of spectral emission bands. Calculated some physical parameters of neutral gas cometary atmosphere and dusty cometary atmosphere.Built distribution of general and reflected energy along the slit of the spectrograph.Calculated fluxes, the number of molecules and gas productivity for basic molecular emissions, relative dust productivity.
