In this paper some applications of the Raman spectroscopy on levitated single particles are presented. The levitation of the particles take place by the three mostly used techniques, the ultrasonic levitator, electro dynamical balance, and optical levitation. Raman spectrosopy is used for identification of substances, for investigation of fluid phase equilibria of mixtures or for observation of chemical reactions. Additionally information about the form and morphology of the particles could be generated from the Raman spectra.
