The pure rotational level of a molecule in the far-infrared region follows the formula F(J) = BJ(J + 1), where F(J) is the energy of the rotational level with quantum number J and B is the rotational constant. The lowest rotational energy gap in rotational Raman spectrum is
The allowed rotational energy levels of a rigid hetero-nuclear diatomic molecule are expressed as εJ = BJ (J + 1), where B is the rotational constant and J is a rotational quantum number.
In a system of such diatomic molecules of reduced mass μ, some of the atoms of one element are replaced by a heavier isotope, such that the reduced mass is changed to 1.05μ. In the rotational spectrum of the system, the shift in the spectral line, corresponding to a transition J = 4 → J = 5, is

While measuring the output load capacitance Cgs, n and Cgs, p is not considered. Why?
During the calculation of load capacitance of a 1st stage CMOS inverter, the input node capacitances, Cgs, n and Cgs, p of the 2nd stage CMOS inverter is also considered.
Moment of inertia can be regarded as the measure of the rotational inertia of the body.
