Please only answer part ii

a) The rotational spectrum of carbon monoxide, *CYO where x and y indicate isotopes, with bond length of 1.13 Á, has two adjacent absorption lines at 15.36 and 19.20 cm-1, respectively. The centrifugal distortion constant, D, and vibrational frequency of the bond, , have values of 6.2 × 10-6 cm-1 and 2170 cm-1, respectively. Use the equations below to answer the following: h3 D : cm-1 32n412r2 kc k = 4@²n?c?µ i) Determine the origin of the rotational level giving rise to the two observed resonance lines. Calculate the energy of the ground, first and second excited rotational levels, expressed as a wavenumber in units of cm-1, assuming a rigid-rotor model. ii) ii) Calculate the relative populations of the first and second excited rotational levels at 300 K. iv) Using the spectroscopic data, calculate the reduced mass of XCYO.
