Abstract
The temperature dependencies (from 295 K to melting temperatures) of optical activity for the KDP group crystals (KH 2(1−x) D2x PO4, NH 4 H 2 PO 4 , RbH 2 PO 4 , and CsH 2(1−x) D 2x AsO 4 ) for wavelengths λ = 633 nm are measured. The experimental technique related to the HAUP is used. Insignificant influence of deuteration on the optical activity of these crystals is detected.
