From a review of existing correlations for K(P) the partition coefficient of semi-volatile organic chemicals (SOCs) between aerosol and gaseous phases, it is suggested that the octanol-air partition coefficient (K(OA)) may be a valuable direct descriptor of SOCs volatility and may be preferable to the use of the experimentally inaccessible subcooled liquid-vapor pressure. Successful two parameter correlations are developed between log K(P) and log K(OA), and an even simpler one parameter correlation is suggested that the ratio K(P)/K(OA) is approximately constant for a class of SOCs

Abstract
From a review of existing correlations for K(P) the partition coefficient of semi-volatile organic chemicals (SOCs) between aerosol and gaseous phases, it is suggested that the octanol-air partition coefficient (K(OA)) may be a valuable direct descriptor of SOCs volatility and may be preferable to the use of the experimentally inaccessible subcooled liquid-vapor pressure. Successful two parameter correlations are developed between log K(P) and log K(OA), and an even simpler one parameter correlation is suggested that the ratio K(P)/K(OA) is approximately constant for a class of SOCs
