High Resolution Coherent Raman Spectroscopy: Studies of Molecular Structures
One of the main advantages of the non-linear coherent Raman techniques is the high resolution that can be achieved in rovibrational spectroscopy. Typically an instrumental function of the order of several thousandths of a wavenumber is routinely achieved in SRS or CARS experiments. Since the first recording of the stimulated Raman spectrum of 12CH4 in 1978 , numerous studies of molecules have been performed [2–8]. We have built a stimulated Raman experiment in Dijon in which particular attention has been paid to the frequency measurement of the Raman lines . We will describe the application of our experiment to a wide variety of molecules over the last few years: linear molecules, spherical top molecules, and also symmetric top molecules.
