The energy of a vibrating molecule is quantized much like theenergy of an electron in the hydrogen atom. The energy levelsof a vibrating molecule are given by the equation En= (n + 1/2 ) hv where n is a quantum number with possible valuesof 1,2,3... and v is the frequency of the vibration. The vibrationfrequency of HCl is approximately 8.85 x 1013s-1 . What minimum energy is required to excite avibration in HCl? What wavelength of light is required toexcite this vibration?
