Abstract

A new classification scheme for spiral galaxies (Block & Puerari 1999) has been developed which classifies galaxies on the basis of their near-IR arm morphology. This 'dustpenetrated class' predicts a correlation between spiral arm pitch angle and rotation curve type (or shear rate A=ω, where A is the first Oort constant and ω is rotational velocity - Block et al. 1999; Fuchs 2000). If such a correlation exists, it would provide a physical basis for this classification scheme.
