Chapter 11, Problem 11.56E

(a) Using the he expression for the energy of a 3-D rigid rotor, construct the expression for the energy difference between two adjacent levels, E ( l + 1 ) E ( l ) . (b) For HCl , E ( 1 ) E ( 0 ) = 20.7 cm 1 . Calculate E ( 2 ) E ( 1 ) , assuming HCl acts as a 3-D rigid rotor. (c) This energy difference is determined experimentally as 41.4 cm 1 . How good would you say a 3-D model is for this system?
