Electrical Conductivity and Equation of State of Liquid Nitrogen, Oxygen, Benzene, and 1-BUTENE Shocked to 60 Gpa.

Measurements are reported for the electrical conductivity of liquid nitrogen (N(,2)), oxygen (O(,2)) and benzene (C(,6)H(,6)), and Hugoniot equation of state of liquid 1-butene (C(,4)H(,8)) under shock compressed conditions. The conductivity data span 7 x 10('-4) - 7 x 10('1) (OMEGA)(' -1)cm('-1) over a dynamic pressure range 18.1 - 61.5 GPa and are discussed in terms of amorphous semiconduction models which include such transport phenomena as hopping, percolation, pseudogaps, and metallization. Excellent agreement is found between the equation-of-state measurements, which span a dynamic pressure range 12.3 - 53.8 GPa, and Ree's calculated values which assume a 2-phase mixture consisting of molecular hydrogen and carbon in a dense diamond-like phase. There is a 2 1/2 fold increase in the thermal pressure contribution over a less dense, stoichiometrically equivalent liquid.
