Write down an 4. expression for the rotational energy of a molecule, defining terms used (b) from part (a), derive an expression for the wavelength of a pure rotational transition between two adjacent rotational levels. define any terms you introduce. (c) the longest wavelength in the pure rotational spectrum from co is 2.58 mm. use this information to deduce the separation between the c and o atoms in the molecule. the atomic masses of c and o are 12.0 and 16.0, respectively.

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.
