LASER RAMAN SPECTROSCOPY,evel. The Raman spectrum can be analyzed in terms of the molecular components or functional groups thus providing a “fingerprint” of the molecule. The Raman effect was first observed in 1928 by C.V. Raman and K.S. Krishnan , but wide application was delayed until the development of the laser. The

Ivan Kurilla,Victoria I. Zhuravlevapin (. = ½), as in a hydrogen atom. Since the electron spin and nuclear spin can each be oriented with or against the external magnetic field, there are four possible energy levels as shown in Figure 4.1. The two electron spin eigenfunctions are denoted by α. and β., whereas the two nuclear spin wav
