The lines of the rotational spectrum of HBr are 5.10 x 10^11 Hz apart in frequency. Find the internuclear distance in HBr. (Notes: Since the Br atom is about 80 times more massive than the proton, the reduced mass of an HBr molecule can be taken as just the 1H mass.)
8. Calculate the moment of inertia and the energy in the J = 1 rotational state for ¹H₂ in which
the bond length of ¹H₂ is 74.6 pm. The atomic mass of ¹H is 1.0078 u.
Assume that the states of the π electrons of a conjugated molecule can be approximated by the wavefunctions of a particle in a one-dimensional box, and that the magnitude of the dipole moment can be related to the displacement along this length by μ = −ex. Show that the transition probability for the transition n = 1 → n = 2 is non-zero, whereas that for n = 1 → n = 3 is zero. Hints: The following relation will be useful: sin x sin y = 1/2cos(x − y) − 1/2cos(x + y). Relevant integrals are given in the Resource section.
