Do you expect the energy of the transition from state 3 to state 4 for 2H19F to be larger or smaller than what you computed in part c, assuming that the bond length does not change? Explain your choice based on the relevant equations, or calculate the energy for this transition.

Question

This question pertains to the heteronuclear diatomic 1H19

  1. Given that the bond length of 1H19F is 0.91 angstrom (1 angstrom = 10-10m), calculate the moment of inertia.
  2. Calculate the rotational constant (in J) for the diatomic in part a.
  3. Using your value for the rotational constant in part b, determine the energy of the transition from state 3 to state 4 (in J).
  4. Do you expect the energy of the transition from state 3 to state 4 for 2H19F to be larger or smaller than what you computed in part c, assuming that the bond length does not change? Explain your choice based on the relevant equations, or calculate the energy for this transition. 

 

Steps 1, 2 and 3 have already been found. I need help with the last question only but I haven't been able to get it solved since there can only be three questions answered. The following answers for step 1-3 are below. 

1. moment of inertia = 1.30 × 10-47 kgm2

2. rotational constant = 21.5 cm-1

3. Energy required from transition n= 3 to n= 4 is 3.42×10-27 J
