Molecular desgin for a narrow potential surface curve

[HAYAO]

Rather a short question, but what kind of design can be used for a narrow potential surface curvature in molecules?

Please rephrase. It is hard to tell what you are asking.

Sorry, it wasn't very clear.

Well I am talking about how to make energy potential curve (surface) narrow in molecules.

Considering that energy potential curve can be approximated to a degree with Hooke's law, the potential curve can be made narrower by making the spring constant larger.
That means stronger bonds in molecules, but I am not quite sure specifically how "strong bonds" can be created.

I am specifically talking about organic molecules that are not necessarily strong. I am talking about within these weak molecules, what could be the strongest, therefore a molecule with narrow energy potential curve.
