Abstract
Nitrogen is the most important impurity found in natural diamonds, affecting properties as diverse as colour1 and thermal conductivity2. Consequently it is important to distinguish between the different molecular forms adopted by the nitrogen. Improved data for obtaining the relative concentrations of two of the most common molecular forms are now presented. These data are then applied to a set of diamonds taken from one source and it is confirmed that the relative concentrations of the different forms of the nitrogen are intimately related to each other.
