Scientific paper

Optical CCD images and spectra, 21-cm H I line observations, and radio continuum and FIR maps of six members of the NGC 7448 group of galaxies were studied: NGC 7448, the compact NGC 7463/64/65 subgroup, UGC 12313, and UGC 12321. No clear evidence of ongoing catalcysmic interactions between the group members was found, although the presence of the merger-type galaxies NGC 7464 and 7465 indicates that such events did take place in the more distant past. Signs of recent interactions of a less violent nature are also seen.
