Partition Function Ratios for Molecules Containing Nitrogen Isotopes

Abstract

Nitrogen isotopic partition function ratios have been calculated for the following molecules and ions: N₂, N₂O, NO, NOCl, NO₂, NO₂^—, NO₃^—, and N₂O₄. All available isotopic and anharmonic data have been used, and values of Q¹⁵/Q¹⁴ are tabulated for temperatures at intervals from 100°K to 600°K. Isotopic equilibrium constants calculated from the partition function ratios are compared with those that have been observed experimentally.
