Webacidic). Finally, COSMOtherm predicts liquid–liquid-phase separation in systems containing water and monoterpene-derived organosulfates. The COSMOtherm-estimated prop-erties support the observed stability of organosulfates as SOA constituents and their long-range transport in the atmosphere but also show significant variation between ...
WebCOSMOtherm calculates the activity coefficient of compound iwith mole fraction x iusing the pseudo-chemical potentials at composition fx ig( i (x i)) and at the reference state ( i (x ;T;P)). By default, the reference state used in COSMOtherm is the pure compound (labeled as convention I; Levine, 2009): ln I i(x) = i (x i) ;I i (x;T;P) RT (1) WebI don't have access to either of the dedicated COSMO programs, but at least the input for COSMOtherm seems pretty straightforward. In an input file (name.inp), you would at minimum write: ctd=name.ctd #Identifier f=name.cosmo This would be run using cosmotherm name.inp from the commandline. Share Cite Improve this answer Follow
