WebThis brings us (finally) to the concept of principal axes of inertia. November 24, 2009 10.4 Principal Axes of Inertia Whenever L and w point in the same direction, this marks a principal axis for the body. For principal axes, we can express this parallelism as L = lw. But since L = Iw, that means the constant of proportionality is the moment ...

This constraint condition can be written as V = −[ω ×a] = [ω ×n]R, (12) 2. and then from Eq. (11) one obtains v = ω ×r0. (13) This is similar to Eq. (7) and describes rotation around a horizontal instantaneous axis that goes through
Weband the Schrödinger Equation for rigid rotor is: i2ℏ2 2I ψ = Eψ. Thus, we get: En = J(J + 1)h2 8π2I. where J is a rotational quantum number and ℏ is the reduced Planck's constant. However, if we let: B = h 8π2I. where B is a rotational constant, then we can substitute it into the En equation and get: En = J(J + 1)Bh.
