Özet

Brillouin light spectra of ethanol in a temperature range from 10 to 45 degrees C were experimentally investigated by a scanning Fabry - Perot interferometer. The measurement of spectra were performed at a detection angle of 90 degrees, which is indicated by decreased elastically scattered light. The effect of detection angle in the range 70 to 110 degrees was also observed. A strong dependence of the Brillouin shift on temperature and detection angle was found. The results are summarized in graphical form.
