Homework Statement
Sulfur hexafluoride is a centrosymmetric molecule with four infrared inactive vibrational modes: 346 cm-1 , 524 cm-1 , 643 cm-1 and 775 cm-1 The Raman spectrum of a liquid sample of SF6 (held at elevated pressures) was measured with a laser that has a centre frequency of 532.0 nm. What are the wavelengths of the Stokes and Anti-Stokes lines?
Homework Equations
The Attempt at a Solution
λ= 532.0nm corresponds to v~ = 18796.99cm-1
The vibrational nodes given are smaller than 18796.99,cm-1 so on the Raman spectra, the given wavelengths are the wavelengths of the Stokes lines and there are no Anti-stokes lines.[/B]
I think this is the answer but I would appreciate some help if I am wrong :)
