- Having one or more atom in the molecule consisting of a number of atoms
- Having more than one atom inside molecule; consisting of a number of atoms.
- Having a valence greater than one.
Since Much Smaller Values Are Found For More Complex Molecules, We May Suppose That, In These Cases, The Energy Of Rotation Of A Polyatomic Molecule May Be Greater Than Its Energy Of Translation, Or Else That Heat Is Expended In Splitting Up Molecular Aggregates, And Increasing Energy Of Vibration.
