Electric field induced second harmonic generation (EFISH) experiments in the swivel cell: New aspects of an established method

“…Table 2 shows the values for b, which were obtained with the swivel method and the results other groups have obtained from measurements in wedge cells. Exceptions are dye C, the kb of which our group has published earlier, 44 parison), this is pretty good agreement. In order to show the reproducibility of our measurements we have also given the error bars for all of our results.…”
