We present results of the processing of high-resolution spectra of the comet obtained on July 3-4, 2005. The comet 9P/Tempel 1 were observed with long-slit spectrograph installed in the Prime focus of the 1-m Zeiss telescope of the SAO of the RAS on July 3-4, 2005 (Mount Pastukhov, Nizhny Arkhyz, Northern Caucasus, Russia) and with long-slit spectrograph installed on 1.6-m reflector in Brazil. The observations were obtained before and after collision of the copper impactor of the Deep Impact spacecraft with the nucleus of short-periodic comet 9P/Tempel 1. The detailed identification of emission lines in the spectra was made. Physical parameters (velocities of outflow, life time and rate of gas-productivity of the CN, C2 and C3 molecules) of the cometary neutral atmosphere are calculated. The presence of the cometary luminescence continuum (non-solar origin) and changes in the comet spectra are discussed.
