We investigate spectral and photometric properties of star forming complexes (SFC) in external galaxies. The SFCs wereselected in 17 nearby galaxies of spiral or irregular type, having inclinations less than 45 ◦ and distances less than 15 Mpc.To identify SFCs, we developed a method based on matching sources of emission at 160µm (cold dust) and 8µm (polycyclicaromatic hydrocarbons). Using photometry in dierent spectral bands, correlations between SFC properties for spiral andirregular galaxies were considered. Spectral and kinematic analysis was carried out for several SFCs, and a method to detectgas motion patterns in these SFCs was suggested.
