15. The separation between the first Stokes and corresponding anti-Stokes lines

Question

15. The separation between the first Stokes and corresponding anti-Stokes lines of the rotational Raman spectrum in terms of the rotational constant, B is b) 4B a) 2B The total magnetic flux that passes through the ring is a) zero c) 6B d) 12B 16. A superconducting ring is cooled in the presence of a magnetic field below its critical temperature (Te) b)n ne d) c) 4Tte 17. In a cubic crystal, atoms of mass Mi lie on one set of planes and atoms of mass M2 lie on planes interleaved between those of the first set. If C is the force constant between nearest neighbour planes, the frequency of lattice vibrations for the optical phonon branch with wave vector k- 0 is b) c) d) zero M 2M

Explanation / Answer

15. The separation between the first stokes and coresponding anti-stokes lines of the roraional Raman spectrum in terms of the rotational constant, B is

OPTION b) 4B so from its measurement I can be determined and then used to find the bond lengths exactly as in the case of microwave spectroscopy

16.  A superconducting ring is cooled in the presence of magnetic field below its critical temperature(Tc). the total magnetic flux that passes through the ring is

OPTION a) zero

17. OPTION a)
