Question

the first stoked in the rotational raman spectrum of N14 N15 is observed at 11.5416 cm-1. what is the nuclear distance?​

Answer 1

Stokes lines are of longer wavelength than that of the exciting radiation responsible for the fluorescence or Raman effect. Anti-Stokes lines are found in fluorescence and in Raman spectra when the atoms or molecules of the material are already in an excited state (as when at high temperature).
