 Notes:
   Table 1  a  Solubility values were calculated by the authors from their smoothed air-water partition coefficient (KAM) by assuming KAM values obtained at infinite dilution were valid at the saturation pressure of (1).

 Method/Apparatus/Procedure:
   Air-water partition coefficents were measured by saturating a portion of water by a stream of nitrogen containing a known vapour concentration of (1). After equilibration, the dissolved (1) was absorbed in a porous polymer trap and the entrapped (1) analysed by gas chromatography. The method and apparatus are described in detail in ref 1.

 Source and Purity of Materials:
