The allowed energy levels for a rigid rotator are given by E 27 J J 1 which can also be expressed in the rotational term F J where F J where B E hc h 8 cl BJ J 1 is the rotational constant and 2hcl J J 1 J J 1 h 8n cl If the bond length in 2C 4N is 117 pm and its force constant is 1630 N m 1 As the molecule rotates more e nergetically with increasing J the c entrifugal force causes the bond to stretch slightly Write down the rot ational energy by taking the centrif
