5. Chemists use infrared absorption spectra to identify chemicals in a sample. In one sample, a chemist finds that light of wavelength 5.8 m is absorbed when a molecule makes a transition from its ground harmonic oscillator level to its first excited level. a. Find the energy of this transition. b. If the molecule can be treated as a harmonic oscillator with mass 5.6 x10-26 kg, find the force constant. 6. The ground-state energy of a harmonic oscillator is 5.60 eV. If the oscillator undergoes a transition from its n = 3 to n = 2 level by emitting a photon, what is the wavelength of the photon?
