Common Information for Q. 2 and Q.3. Shown below is a vibrational rotational spectrum for a diatomic molecule with 100 kg recorded at temperature T. h reduced mass = TTTTT TTTTTTTTT TTTT R(2) P2) P(4) 0.8 R0) R(4) P(6) 0.6 0.4 R(8) P(8) 0.2 R(10) P(10) R(12) P(12) 0.0 L LUUL LL LLLL 0.0 3000 3100 2900 2800 2700 2600 Wavenumber/cm Moment of inertia (Kg m-) is (a) 1.0 x 1046 Determine the correctness or otherwise of the following Assertion (a) and the Reason (Uj- Assertion (a) : Usuallysymmetric vibrations give rise to intense Raman lines. NoT ones are usually weak and sometimes not observed. Reason (r): Change in dipole is the highest during svmmetric vibrations than the enang the non-symmetric ones. (a) Both (a) and (r) are true and (r) is the correct reason for (a). (b) Both (a) and (r) are true but (r) is not the correct reason for (a) (c) Both (a) and (r) are false (d) (a) is true but (r) is false. (b) 1.2 x 10-47 (c) 5.0x 104 (d) 2.5x 1047 metric uring
