Inner and outer velocity gradients, residuals from synthetic rotation curves for field spirals, and M/L gradients are used to study the rotation curves of spiral galaxies. A good correlation is found between the outer gradient of the rotation curve and the galaxy's distance from the cluster center, with a similar effect noted in the residuals between the observed and synthetic rotation curves. A correlation is also shown to exist between the M/L gradient across a galaxy and the galaxy's position in the cluster. The results suggest that the inner cluster environment may strip away some fraction of the mass in the outer halo of a spiral galaxy or may not allow the halo to form. 27 references.
