b) The photon energy in the transition from the level v = 0 to v = 1 is: Eph = ∆E = E1 – E0 = 3/2hv0 – ½ hv0 = hv0; Since the energy of a photon is given by Ephoton = hv, the frequency of the transition from the first to the next second vibrational level is: Eph = hv; λ = c/v0 = 3*108/8.963*1013 = 3.345 * 10-6 m = 3345 nm. c) Hydrogen atom (H2) vibrational spectra; HF show rotational or vibrational spectra, since others are linear molecules. CO will show rotational spectra while H2 will no.
