The authors have analyzed an IUE echelle image of nova V693 Coronae Austrinae 1981 obtained 12 days after its outburst. Broad (30 - 40 Å full width) emission lines dominate its spectrum and generally confirm the difficult identifications of emission features present in its low-resolution spectrum taken 12 days after outburst. Numerous sharp absorption lines of low-, intermediate-, and high-ionized metal species are present in the line of sight (l = 357°, b = -15°) to the nova but none show any appreciable velocity shifts beyond a deduced average interstellar medium velocity of >vism< = -17 km s-1. Approximate column densities have been determined, by using the weak line approximation and, wherever possible, by constructing curves of growth. A hydrogen column N(H I) > 1010cm-2 is deduced.
