Q: In the Raman spectrum of N₂, the incident radiation is 488 nm (from Ar⁺ laser). The Raman shift for the vibrational transition is 2331 cm⁻¹. Calculate the wavelength of the Stokes line.
Solution: Convert incident wavelength to wavenumber: [ \bar\nu_i = \frac1\lambda_i = \frac1488 \times 10^-7 \text cm = 20492 \text cm^-1 ] Stokes wavenumber: [ \bar\nu_s = \bar\nui - \Delta \bar\nuvib = 20492 - 2331 = 18161 \text cm^-1 ] Wavelength: [ \lambda_s = \frac1\bar\nu_s = \frac118161 \text cm^-1 = 5.506 \times 10^-5 \text cm = 550.6 \text nm ]
