- TL;DR Summary
- I have let's say a hydrogen molecule and the optimum distance is ##r_0##. When I know that the range of binding interactions is ##r## from the optimum distance, what does it mean? Is it a deviation of a vibrating hydrogen atom?

I can look at it as if a vibrational motion of the atoms was a simle harmonic motion. So I can consider one of the two atoms to be at rest and the second one to vibrate. Its deviation can be written as ##x(t)=r(t)-r_0##.

When I know that the hydrogen molecule stops exiting when the range of binding interactions is ##r## from the optimum distance, does it mean that this ##r## is a deviation ##x##? Or is it ##r(t)##, the distance of the atoms with respect to time?
