Observations are proposed using the FOS to accurately measure the far-ultraviolet (~1200-1800A) spectrum of Titan at ~3A resolution, which has been observed previously only by the Voyager Ultraviolet Spectrometer (UVS) at very low spectral resolution (~30A). Models of the bright emissions from atomic and molecular nitrogen and N+ in the Voyager data provide poor fits longward of Ly-alpha. In addition, several unidentified emissions remain which cannot be explained by N2 or its dissociation products, including a strong feature at ~1336A. Positive identifications of these emissions will help determine the relative contributions by magnetospheric particle precipitation, photoelectrons, and direct solar excitation to the observed UV dayglow, and will allow comparison with UV observations of the Earth's airglow and aurora. In addition, solar reflected light longward of Ly-alpha will be detected and complements the dayglow observations, allowing detections or upper limits to be placed on the abundance, distribution and chemistry of minor constituents such as hydrocarbons, nitriles, and hazes, which are of considerable interest because of the striking resemblance between Titan's atmosphere and the primitive atmosphere of the Earth.
