Solid vapor pressure for five heavy PAHs via the Knudsen effusion method

► We report on vapor pressures and enthalpies of fusion and sublimation of five heavy PAHs. ► Solid vapor pressures were measured using Knudsen effusion method. ► Solid vapor pressures for benzo[b]fluoranthene, and indeno[1,2,3-cd]pyrene have not been published in the open literature. ► Reported subcooled liquid state vapor pressures may or may not lend themselves to correction to sublimation vapor pressure. ► Subcooled liquid state vapor pressures might sometimes actually be closer to actual solid state sublimation vapor pressures.
