P7E.5 In infrared spectroscopy it is common to observe a transition from the v = 0 to v = 1 vibrational level. If this transition is modelled as a harmonic oscillator, the energy of the photon involved is ħo, where o is the vibrational frequency. (a) Show that the wavenumber of the radiation corresponding to photons of this energy, v, is given by v=@/2nc, where c is the speed of light. (b) The vibrational frequency of 'H*Cl is w = 5.63 x 10“s"; calculate v. (c) Derive an expression for the force constant k, in terms of v. (d) For "C"O the v = 0 →1 transition is observed at 2170 cm. Calculate the force constant and estimate the wavenumber at which the corresponding absorption occurs for "C*O. Use integer relative atomic masses for this estimate.
