A water molecule is placed in the xy plane of a coordinate
system with oxygen in origin, such that each H atom has the same
distance to the x-axis. The distance between oxygen and hydrogen is
0.958 Å and the angle between the three atoms is 104.48. The three
atoms are considered point masses and the molecule is assumed to be
a rigid body. The mass of hydrogen is 1.674*10^-27 kg, the mass of
oxygen is 2.657*10^-26 kg, the mass of deuterium is
3.344*10^-27
- Calculate the moment of inertia with respect to the three
coordinate axes for H2O. Repeat the calculation for D2O that has
the same geometry.
- Find the mass center of the H2O molecule.
- What will be the inertia moment of the H2O molecule for
rotation about an axis through the mass center and parallel to the
z axis? Repeat for the two axes parallel to x and y and through the
center of mass.
