The two nuclei in the carbon monoxide (CO) molecules are 0.1128 nm apart.  The mass of the carbon atom is 1.993x10-26 kg.  The mass of the oxygen atom is 2.656x10-26 kg.  Spectroscopic measurements show that adjacent vibrational energy levels for the CO molecule are 0.269 eV.   What is the effective spring constant of the CO molecule? (Give your answer in N/m.)
(a) How much energy is required to cause an electron in hydrogen to move from the n = 2 state to the n = 5 state? in J(b) Suppose the atom gains this energy through collisions among hydrogen atoms at a high temperature. At what temperature would the average atomic kinetic energy 3/2 * kBT be great enough to excite the electron? Here kB is Boltzmann's constant. in K
