Spectral observations of 10 nests of interacting galaxies have been carried out in 1977-1985 with the image-tube UAGS spectrograph in the main focus of the 6-m telescope of the Special Astrophysical Observatory. The radial velocities of the components were studied and their rotation curves, luminosities, and masses were obtained. The objects VV 148, 566, 575 and possibly VV 270 may be single SBd or IBm galaxies with unusually large H II regions, about 1 kpc or larger. VV 125 was found to be an Scd spiral. The other objects have turned out to be interacting pairs or multiple systems. The strong interaction is observed in the pairs VV 273 and VV 564, and in VV 243 as well. Noncircular motions were found in the main component of VV 273 and in VV 564. VV 131 may be a nest of three dwarf galaxies.
