        [1913 Webster]
     Note: Chemical formul[ae] consist of the abbreviations of the
           names of the elements, with a small figure at the lower
           right hand, to denote the number of atoms of each
           element contained.
           [1913 Webster]
     Empirical formula (Chem.), an expression which gives the
        simple proportion of the constituents; as, the empirical
        formula of acetic acid is C2H4O2.
     Graphic formula, Rational formula (Chem.), an expression
        of the constitution, and in a limited sense of the
        structure, of a compound, by the grouping of its atoms or
        radicals; as, a rational formula of acetic acid is
        CH3.(C:O).OH; -- called also structural formula,
        constitutional formula, etc. See also the formula of

From The Collaborative International Dictionary of English v.0.48 :

  Structural formula \Struc"tur*al form"u*la\ (Chem.)
     a symbolic representation of the structure of one molecule of
     a chemical compound, showing the attachments of the atoms to
     each other, and representing their arrangement in space; the
     spatial representation is symbolic and approximate, and it
     may or may not depict the stereochemical relations of the
     bonds. Distinguished from empirical formula. See also
     Rational formula, under Formula.

From WordNet (r) 3.0 (2006) :
