Structure of liquid nitrogen

Abstract

The experimentally determined electronic radial distribution function for liquid nitrogen at 7 atmospheres and -193°c is reported, ndicating an average coordination shell centred at 4·0 å containing 15 molecules. Subsidiary peaks in the distribution at about 2·2 å are shown to very likely arise from truncation of the Fourier integral. Analysis reveals that a restricted increase in the range of diffraction data may actually increase the prominence of certain error features.
