Can anyone explain about vibrations and resonance in a hydrogen chloride molecule in terms of physics?

Question

Also, where can I find the graph of energy absorbed by the molecules vs frequency of incident radiation? How do I find its bond strength in terms of physics?

Answer 1

I have found a link which answers all the question with H AND Cl for example

For a graph of energy versus frequency, you must know that energy is proportionnal to frequency
E = hf with E joule, h =6.6210^-34 Js so ,you willnot find a graphic for a line!
