We present CORAVEL radial velocities and high precision UBV and DDO photoelectric photometry for a sample of red giant candidates of the open clusters NGC 6192, NGC 6208 and NGC 6268. We discovered 3 new spectroscopic binaries and determined mean radial velocity, reddening and metallicity for the three clusters. We also examined the properties of a sample of 42 inner disk open clusters projected towards almost the same direction.
