The definition of the integer system dependent parameters is as follows:

• NTERM: (the number of potential surfaces involved: this should be 3 in this case). This parameter can not be changed
• IOP: ortho/para label for rotational states of diatomic. If IHOMO = .True. then
  • if IOP = 1: only para states are included in channel expansion
  • if IOP = -1: only ortho states are included in channel expansion
• JMAX: the maximum rotational quantum number of diatomic

  The definition of the real system dependent parameters is as follows:

• BROT: rotational constant of diatomic molecule
• ASO: spin-orbit constant of ³P atom
