The expressions for the P-, Q-, and R-branches, assume that the moment of inertia of the molecule is the same in the excited vibrational states as in the ground state. Derive expressions for the positions of the lines without making these assumptions.
The dipole moment of a compound depends on the resultant partial charges based on the electronegativities of the individual constituents present in the compound. Based on this definition, write the resulting dipole moment in the following compounds
