dihedrals
%FORMAT(10I8) (IP(i),JP(i),KP(i),LP(i),ICP(i), i=1,NPHIA) IP : atom involved in dihedral "i", dihedral does not contain hydrogen JP : atom involved in dihedral "i", dihedral does not contain hydrogen KP : atom involved in dihedral "i", dihedral does not contain hydrogen LP : atom involved in dihedral "i", dihedral does not contain hydrogen ICP : index into parameter arrays PK, PN, PHASE, ONE_SCEE, and ONE_SCNB for dihedral IPH(i)-JPH(i)-KPH(i)-LPH(i). Note, if the periodicity is negative, this implies the following entry in the PK, PN, and PHASE arrays is another term in a multitermed dihedral.
