Question
a. Given that the bond length of 'H1°F is 0.91 angstrom (1 angstrom = 10-10 m), calculate the
moment of inertia.
b. Calculate the rotational constant (in J) for the diatomic in part a.
c. Using your value for the rotational constant in part b, determine the energy of the transition from
state 3 to state 4 (in J).
d. Do you expect the energy of the transition from state 3 to state 4 for 2H1F to be larger or
smaller than what you computed in part c, assuming that the bond legnth does not change Explain
your choice based on the relevant equations, or calculate the energy for this transition.
