Abstract

Abstract The micro-wave power transmission at 35 GHZ of triammonium hydrogen disulphate (NH4)3H (SO4)2 (NHS) has been investigated between 100 and 300 K. The present work confirms the existence of four phases previously observed by other techniques. In addition, two anomalies observed at 242 and 222 K are reported here for the first time.
