Abstract High-pressure Raman studies up to 40 GPa have been made on solid ND3 at room temperature. Features of external and internal modes are compared to that of solid NH3 and mode assignments are proposed in solid phase IV (p⩽3.8 GPa). In contrast with NH3, which transforms to a cubie phase at 15 GPa, solid IV ND3 was observed to be stable up to 40 GPa, the upper limit of the present investigation. It is concluded that bond symmetrization in ND3 will occur above that of NH3.
