Summary
As in the case of quartz (Chandrasekharan, 1948), using the property of optical activity, the selection rules for Raman lines of sodium chlorate have been experimentally verified using λ 2537 excitation for two different orientations of the crystal. Its 15 Raman lines have been classified as follows into the various symmetry classes possible for a cubic crystal:— 70 (E), 83 (F), 103 (F), 123 (F), 131 (A), 179 (E), 482 (E), 487 (F), 627 (A+F), 933 (F), 936 (A), 959 (E), 966 (F), 984 (F), 1026 (−). The results agree with earlier ones of Couture and Mathieu (1948) except for the Raman line 131 cm.−1 which they classify as belonging to Class E.
The Brillouin components are well polarised and weaker than the symmetric Raman line 936 cm.−1
