  Molecular \Mo*lec"u*lar\, a. [Cf. F. mol['e]culare. See
     {Molecule}.] (Phys. & Chem.)
     Pertaining to, connected with, produced by, or consisting of,
     molecules; as, molecular forces; molecular groups of atoms,
     etc.
     [1913 Webster]


  
     {Molecular attraction} (Phys.), attraction acting between the
        molecules of bodies, and at insensible distances.
  
     {Molecular weight} (Chem.), the weight of a molecule of any
        gas or vapor as compared with the hydrogen atom having
        weight of 1 as a standard; the sum of the atomic weights
        of the constituents of a molecule; thus, the molecular
        weight of water ({H2O}) is 18. For more precise
        measurements, the weight of the carbon isotope carbon-12
        is used as the standard, that isotope having the value of
        12.000. In this systen, now used almost universally, the
        hydrogen atom has a weight of 1.0079.
        [1913 Webster +PJC]
