Deuterated triglycine sulfate crystals are useful as tracers for studying the properties of the compound; they are also of great interest for establishing the effect of ihe replacement of hydrogen by deuterium on the physical properties of the compound. Deuteration was accomplished by the crystallization of the compound from heavywater solution; a more completely deuterated compound was prepared by recrystallizing the material from a glycocoll + H/sub 2/SO/sub 4/ medium dissolved in heavy water. The Curie point of the deuterated material was found to be higher, (58.9 deg C) than the value of 47 to 49.6 deg , reported in the literature for the ordinary material. Optical properties of the two materials are very similar. The temperature dependence of the dielectric constant shows the hysteresis loop, characteristic for ferroelectric materials; the shape of this loop is different from that of the nondeuterated crystal. They can be used on a wide range of temperatures. (TTT)
