Abstract
Low pressure (2, C6H14 (n‐hexane), CH2I2, CHCl3, C6H6, and C6H12 (cyclohexane). In each case, the shock velocity‐particle velocity, U(u), Hugoniot was nonlinear and the shock velocity smoothly approached the sonic velocity as the shock pressure approached zero. Enthalpy‐pressure‐volume equation of state parameters are given for CS2, C6H14, C6H6, and C6H12.
