MM+ / HyperChem examples



 Hi,
  I am using the HyperChem software to prepare a course that will
 introduce undergraduate chemistry students to molecular modelling.
  I would be very much obliged if people could supply me with examples of
 two or more  isomers of the one compound whose relative energies are NOT
 predicted by the MM+ force field.
  Thank you in advance for any help that you can give me.
  Best wishes,
  Paddy.
