Abstract :
[en] A series of about forty long-slit spectra of Halley's comet has been secured in the optical wavelength region, using different instruments, at resolution ranging from 0.05 to 1.6 nm. The interval of heliocentric distance r covered by these observations is 1.7 to 0.9 a.u. before perihelion, while r = 0.95 a.u. after perihelion. The main characteristics of the pre-perihelion spectra are described. In particular, some emissions due to the OH[SUP]+[/SUP] (0,1) and CH[SUP]+[/SUP](1,0) bands have been detected for the first time.
