STIS near-IR longslit spectroscopy of the nearby S0 galaxy NGC 7332 was obtained of the Ca II triplet absorption lines at ~ 8600 Angstroms. We use the Fourier correlation quotient method (Bender 1990, A&Ap, 229, 441) to extract the line-of-sight velocity distribution in the inner 4'' of the galaxy. Combined with ground-based imaging and spectroscopy (Fisher, Illingworth & Franx 1994, AJ, 107, 160) and HST WF/PC-1 imaging (Lauer et al. 1995, AJ, 110, 2622) these data were fitted with three-integral dynamical models developed by K. Gebhardt, to investigate the nuclear stellar dynamics and to search for evidence of a massive black hole. Since Maggorian et al. (1998, AJ, 115, 2285) find it to be the best case for M=0, NGC 7332 is an important object.
