How to Calculate the Wavenumber in Raman Spectroscopy for Ethene?

Click For Summary
To calculate the wavenumber in Raman spectroscopy for ethene, the relationship between wavelength and wavenumber must be understood. The wavenumber is defined as the reciprocal of the wavelength in centimeters, but adjustments are needed for Stokes and anti-Stokes scattering. Given the laser radiation of 488.0 nm and the observed line at 540.0 nm, the calculation involves determining the difference in energy levels. The discussion emphasizes that while the concept is straightforward, it requires a deeper understanding of the principles behind Raman spectroscopy. Proper calculation is essential for accurate interpretation of spectral data.

Homework Statement


The Raman spectrum of ethene, obtained using 488.0nm radiation from a laser, shows an intense line at 540.0nm. Calculate the wavenumber for this vibration


I know that you get stokes, anti-stokes and rayleigh scattering. Not sure how to calculate the wavenumber though . I know its not as simple as taking the reciprical of the wavelength though


thanks

Try to Wiki Raman spectroscopy. Pretty simple IMO but not as simple as just asking for the answer, eh?
