In a Raman experiment laser of 633 nm is being used (wave number = 15,797 cm-1) on a sample. Consider a particular stokes transition that leads to a scattered light at wavenumber 13567 cm-1. (a) What will be the wavenumber of the anti-stokes lines for the similar transition? (b) What is the energy of this transition? (c) If laser light of 530 nm is used what will be the wavenumber of the scattered light due to the same stokes transition?

The wavenumber of the incident radiation in a Raman spectrometer is 20 623 cm−1. What is the wavenumber of the scattered Stokes radiation for the J = 4 ← 2 transition of 16O2? (I solved for delta E = E(j=4) - E(j=2) and then used delta E = h*v and wavenumber = v/c .. but I think I messed up something because I got an extremely small wavenumber. Could you possibly follow this format?)

A laser emitting at 350 nm passes through a cuvette containing water. Due to the Raman effect, as the laser passes through water, it loses energy to excite vibrational modes of water molecules. Consider only the vibrational level in water corresponding to the stretching of the OH bond which occurs at about 3500 cm−1. What is the wavelength of the laser radiation after it went through the water if the energy is lost due to the excitation of one vibrational...
