Let's try to get some idea how fast a water molecule may rotate. Assume that the molecule rotates around the vertical axis going through the O atom on the plane of the molecule as shown below. The total rotational kinetic energy is (3/2)kbT. Estimate the angular rotational velocity (0) of the water molecule. T = 37 C. 0 d 0 r H H d= 0.95 0 = 104.5 Erotational = (1/2) I 02 I = 2 mr?, my is the mass of the hydrogen atom
