Problem 6.178

Calculate the wavelengths of the red and violet satellites, closest to the fixed line, in the vibration spectrum of Raman scattering by F2\mathrm{F}_ {2} molecules if the incident light wavelength is equal to λ0=\lambda_ {0}= =404.7nm=404.7 \mathrm{nm} and the natural vibration frequency of the molecule is ω=2.151014 s1\omega=2.15 \cdot 10^{14} \mathrm{~s}^{-1}

Reveal Answer
λ=λ0/(1ωλ0/2πc)=423 and 387nm\lambda=\lambda_{0} /\left(1 \mp \omega \lambda_{0} / 2 \pi c\right)=423 \text { and } 387 \mathrm{nm}
