Unformatted text preview: HOH bond angle is 104.45 degrees. Hints: using the O atom as the origin, determine the center of mass and then compute the moment of inertia tensor using x, y, z axes of your choice. You should find all products of inertia to be zero so that the three moments you calculate are the principal moments. b) Draw a diagram of the water molecule and label the a, b, and c axes. Also show the direction of the dipole moment of the molecule. What type/s of transitions do you expect (e.g. atype)? c) Use Table 6.2 (Bernath, page 196) to calculate the frequencies of the allowed Δ J = 1 transitions for J’ = 2 and J” = 1. 4. Radioastronomers are able to detect molecules containing unusual isotopes. At what frequency should an astronomer search for the J = 1 >0 transition of 13 CO? You can estimate B from the 12 CO value of 57.6 GHz....
