Question

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 quantum? You must express the final results in terms of the wavelength of the laser radiation in nm
