P11C.15 The rotational constant for a diatomic molecule in the vibrational state with quantum number v typically fits the expression B, = B,- a(v+}), where B, is the rotational constant corresponding to the equilibrium bond length. For the interhalogen molecule IF it is found that B, = 0.279 71 cm and a = 0.187 m (note the change of units). Calculate B, and B, and use these values to calculate the wavenumbers of the transitions originating from J= 3 of the P and R branches. You will need the following additional information: v = 610.258 cm and x,ỹ = 3.141 cm. Estimate the dissociation energy of the IF molecule.

Transcribed Image Text:P11C.15 The rotational constant for a diatomic molecule in the vibrational
state with quantum number v typically fits the expression B, = B,- a(v+}),
where B, is the rotational constant corresponding to the equilibrium bond
length. For the interhalogen molecule IF it is found that B, = 0.279 71 cm
and a = 0.187 m (note the change of units). Calculate B, and B, and use these
values to calculate the wavenumbers of the transitions originating from J= 3
of the P and R branches. You will need the following additional information:
v = 610.258 cm and x,ỹ = 3.141 cm. Estimate the dissociation energy of the
IF molecule.
