Step 1

The energy in the term of corresponding wavenumber for the rotational region spectra (ƐJ) is calculated as show in equation (1) where h and c is the Planck’s constant and speed of light respectively, I is the moment of inertia, and J is the rotational energy level.

Step 2

The emitted energy in the term of wavenumber is calculated as shown in equation (2). This will give the equation (3).

Step 3

The moment of inertia for the given molecule is calculated as shown in equation (4) where MC12 and MO16 are molar masses of carbon and oxygen, and r is the bond length. The values for r, MC12, and MO16 are substituted...
