We show that resonance-ionization mass spectrometry is an excellent technique for acquiring high-resolution optical spectra of rare isotopes. To demonstrate the potential of this technique, hyperfine spectra of the /sup 2/D/sup degree//sub 3/2/ reverse arrow /sup 2/D/sub 3//sub ///sub 2/ lutetium transition at 22 125 cm/sup -1/ are presented for /sup 176/Lu, /sup 175/Lu, /sup 174/Lu, and /sup 173/Lu. The last-named two are rare isotopes with half-lives of 3.3 and 1.4 years, respectively, whose optical spectroscopy has not previously been explored. Sensitivity is documented by the fact that the total amount of these rare isotopes in our sample was 2 x 10/sup -10/ and 3 x 10/sup -11/ g. Analysis of the spectra confirms that the spin of /sup 174/Lu is unity and yields values for the hyperfine constants and isotope shifts of these nuclei.
