what is the average period of rotation of HCI molecule if it is in the J-1 state. The inter nuclear distance of HCI is 0.1274nm. Given the mass of H and chlorine atoms are 1.673x10-27Kg and 58.06x1027Kg respectively H.W(4):- 1-A:-Calculate the energy and wave-length of the photon absorbed when a Hg"Cl molecule (r. 2.23°A) makes the rotational transition J-0-J-1 and J=1-J-2. B: In what region of the electromagnetic spectrum are these lines found? 2- Suppose that the equilibrium separation in the 'H"CI molecules is the same and equal to 1.27°A. Compute for each molecule A:-The constant B. B: The energy of the first two excited rotationa levels. C:-The frequencies and wave length corresponding to the transition J-0-J-1 and J-1-J=2. Q: What is the necessary condition for a molecule to show rotational spectrum? Q: What is the effect of decrease in the moment of inertia on the energy of the rotational level?
