Bars are considered to be an important fueling mechanism for nuclear starburst activity, and are believed to be a dynamical result of gravitational interactions and merging. Furthermore, in a recent study, Das & Jog (1995) suggest that the dynamical impact of a bar will also have important consequences for cloud properties in the bar and nucleus. NGC 7479 is a barred galaxy with an unusually long and strong bar. At a distance of D=32 Mpc the bar length is ≈10 kpc. We selected NGC 7479 for a study of cloud properties in bars because of its proximity and because molecular gas is distributed along the whole length of the bar (e.g. Quillen et al. 1995).
