Suppose the energy of a vibrating molecule is quantized much like the energy of an electron in the hydrogen atom. The energy levels of a vibrating molecule are specified by the equation
En = (n +1/2)hv, h= 6.626*10-34Js
Where n is the quantum number with possible values of 1, 2.... as well as v is the frequency of vibration. The vibration frequency of HCL is approximately 8.85 *1013s-1. Explain what minimum energy is required to excite a vibration in HCL?
