raman active मीनिंग इन हिंदी

उदाहरण वाक्य

1. Symmetrical stretches and bends, however, tend to be Raman active.
2. Together, this indicates that the transition must be both IR and Raman active.
3. Then, each vibrational mode can be identified as either IR or Raman active.
4. Optical phonons that are " Raman active " can also interact indirectly with light, through Raman scattering.
5. Since nickel is not Raman active, direct Raman spectroscopy of graphene layers on top of the nickel is achievable.
6. Raman active fibers, such as aramid and carbon, have vibrational modes that show a shift in Raman frequency with applied stress.
7. For molecules without a center of symmetry, each vibrational mode may be IR active, Raman active, both, or neither.
8. Not all vibrational transitions are " Raman active ", i . e ., some vibrational transitions do not appear in the Raman spectrum.
9. The rule arises because in a character table there is no irreducible representation that spans both IR and Raman active modes, and so there is no overlap between the two spectra.
10. To determine which modes are Raman active, the irreducible representation corresponding to xy, xz, yz, x 2, y 2, and z 2 are checked with the reducible representation of ? vib.
