Find the natural vibration frequency and the quasielatic force coefficient of an `S_(2)` molecule if the wavelength of the red and voilet satellites, closests to the fixed line, in the vibration specturm of Raman scattering are equal to `346.6` and `330.0 nm`.

Answer» As in the previous problem
`omega= pic((1)/(lambda_(V))-(1)/(lambda_(R)))=(pi c(lambda_(R)-lambda_(V)))/(lambda_(R)lambda_(V))= 1.368xx10^(14)rad//s`
The force constant `x` is defined by
`x= mu omega^(2)`
where `mu=` reduced mass of the `S_(2)` molecule.
Substitution gives `x=5.01N//cm`
