“…AI = ax + by + cz + du + es (9) Rohrschneider first attempted to describe A/ in terms of the first three product terms but found it necessary to consider five terms, which explains the lack of sequence of the solvent terms. The set of test solutes must adequately characterize the principal interactions responsible for retention in gas chromatography: dispersion, orientation, induction, and donor-acceptor complexation.…”

“…The concentration of the -glucose is then determined by subtracting the calculated area of fructose isomer 3 from the area under peak D according to Phillips and Smith (1973). Partial silylation is known to occur when insufficient reagent (HMDS) is provided (Kim et al, 1967;Larson et al, 1974;Ellis, 1969;Bedle, 1969;Supina and Rose, 1970).…”

“…The Rohrschneider/McReynolds system of phase constants [6,15,318,327,328,380,397,[401][402][403], solubility parameters [6], the solvent selectivity triangle of Snyder [336], Hawkes polarity indices [404], dispersion and selectivity indices [331,405], universal indices [406] and various thermodynamic approaches [303,397,404,407] have been the most widely used. Unfortunately, fundamental approaches have not advanced to the point where an exact model can be put forward to describe the principal intermolecular forces between complex molecules.…”
