Infrared and Raman spectra of inorganic and coordination compounds / Kazuo Nakamoto. and Introductory Raman Spectroscopy (Kazuo) are good one to take a look. Also I suggest you to look at Faraday discussions series which you can find in your library. I read the surface enhanced Raman spectroscopy of Faraday discussions and it helped me alot.
