isomer - Collaborative International Dictionary of English v.0.48 :

  Isomer \I"so*mer\ ([imac]"s[-o]*m[~e]r), n. [See Isomeric.]
     (Chem.)
     A compound which is isomeric with another body or compound; a
     compound having the same chemical composition as another
     compound; a member of an isomeric series.
     [1913 Webster +PJC]
  
     Note: An isomer may be a structural isomer, in which some
           of the atoms are bonded to different atoms (as in
           CH3.CH2.NH2 and CH3.NH.CH3), or an optical isomer
           , in which the number and types of chemical
           bonds are identical, but the arrangement of the atoms
           in three-dimensional space is different; the latter are
           also called stereoisomers.
