Abstract
Recent measurements of Nellis, et. al.1,2 provide evidence for shock-induced dissociation in molecular nitrogen and oxygen. Nitrogen shows a dramatic increase in compressibility above about 30 GPa, with densities in the range expected for a monatomic fluid. This effect is much less obvious in the oxygen data, but it is reasonable to assume that dissociation occurs in that case as well. Static measurements on the solid show no evidence of a transition from a molecular to a monatomic form in nitrogen up to 52 GPa3 or in oxygen up to 13 GPa.4 Calculations by McMahan and LeSar5 predict the transition to occur at about 100 GPa in solid nitrogen. Hence, high temperatures are believed to drive shock-induced dissociation.
