A computer‐controlled switching device for a Pockel cell is described. Depolarization ratios of Raman bands are measured accurately as the intensities of alternate polarizations are recorded at a time separation equal to that for a single point measurement. Measurements on liquid chloroform agree to within experimental reproducibility with literature values.
