Four interacting galaxies have been mapped at 10.7 GHz (2.8 cm) with a resolution of 1.2 using the Effelsberg 100-m telescope. Their integrated flux densities at this frequency along with existing data at other frequencies have been used to construct the radio continuum spectra for all four objects. Two galaxies were found to emit strong radio radiation: in case of NGC 520 the bulk of emission comes from its central region. The other one, NGC 2276, has a very bright and extended radio disk. NGC 3448 is generally a weak radio emitter. The barred spiral NGC 3627 exhibits a somewhat strange 'dumbbell' structure. The results have been compared with other radio continuum measurements. The radio morphology of NGC 3627 is discussed in terms of hydrodynamic properties of barred spirals. No interactions are required to explain its radio structure.
