Abstract:
    We have used a deep CO survey (at 115GHz) of the third galactic
    quadrant (May et al., 1993A&AS...99..105M) to derive the physical
    properties of molecular clouds in the outer Galaxy. Within the range
    of this survey, from 194° to 270° in galactic longitude, 177
    molecular clouds have been identified beyond 2 kpc from the Sun.
    Distances have been determined kinematically using the rotation curve
    of Brand (1986, Ph.D. Thesis, University of Leiden) with
    R☉=8.5kpc and Θ☉=220km/s.
