Forbes, Duncan A. ; Kotilainen, Jari K. ; Moorwood, A. F. M. Abstract Recent theoretical studies have suggested that small-scale bars may provide the mechanism for transporting material ("fuel") to a galaxy nucleus. Here we present high-resolution imaging of NGC 7552 in the infrared emission line of H_2_ 2.12 micron which reveals a possible nuclear bar. We also present Brγ imaging which clearly shows the kiloparsec-sized starburst ring previously identified in the radio by Forbes et al. 1994. Although this galaxy appears to possess a small-scale molecular bar and a large reservoir of molecular material, there is no evidence for current activity, either starburst or Seyfert-like, at the nucleus.
