The volume of solid N/sub 2/ having Pm3n space group was measured at 296 K from 5 to 10 GPa using a high pressure, x-ray diffraction technique. The compression of NaF was used as the pressure gauge. From a fit of the compression of the Pm3n structure data converted to the velocity plane, the volumes and bulk moduli are calculated as a function of pressure. From this fit and simultaneous volume measurements of the ..beta..-N/sub 2/ phase and the Pm3n structure, the pressure of transformation from the ..beta..-N/sub 2/ phase to the Pm3n structure is found to be 4.8 GPa. Recently published a priori calculations are shown to agree well with the present data.
