By using bidimensional Fourier techniques, we have analyzed H (1.6μm) images of a sample of 48 spiral galaxies taken from the OSUBSGS. We found that two-armed spirals (m = 2) are the more important structures in the sample, but some galaxies present higher m = 1 (lopsided) or m = 3 (three armed spirals). A weak correlation between m = 2 pitch angles and Eskridge et al. (2002) classification is also evident, but there is no correlation at all between those angles and RC3 classification or Elmegreen arm class.
