• You are working as a spectroscopist, analyzing absorption data for electromagnetic radiation incident on molecular gases. In one experiment, you wish to measure the effective spring constant of a diatomic molecule, consisting of two atoms, each of mass 1.67 ✕ 10⁻²⁷ kg. You know that two masses vibrating on the ends of a spring can be modeled as one particle on the spring with the equivalent particle having the reduced mass

μ = N/m m₁m2 m1 + m2 (See the example Molar Specific Heat of Hydrogen Gas.) When a pure gas of these diatomic molecules is irradiated, an absorption occurs at a wavelength of 2.27 µm. Determine the spring constant (in N/m) that you record in your lab notebook for this molecule. μ = N/m m₁m2 m1 + m2 (See the example Molar Specific Heat of Hydrogen Gas.)
