This macro typesets the aromatic naphthalene ring system,
the fully saturated decalin ring system, and the
1,2,3,4-tetrahydronaphthalene shown in the diagram. The position
numbers 1–8 are specified by the nomenclature rules of
chemistry.

Q
- Arguments 1–8:
- An argument of Q causes
no action. All other argument values are used as the
respective substituent formulas R1–R8.
- Argument 9:
- A value of ``S'' typesets the
ring system with no double bonds (decalin). A value of ``D''
typesets the aromatic system naphthalene with alternating
double bonds. All other argument values draw the partially
saturated system shown above.
