Stability constant (k(m)), enthalpies (-Delta H), entropies (-Delta S) and Gibb's free energy (-Delta G) of gas chromatographic (GC) elution of alcohols, aldehydes, ketones, aromatic hydrocarbons, hetroaromatic compounds and analine from stainless steel column (3m x 3 mm id) packed with [1] OV101 3% [2] OV101 3% + bis(acetylacetone) ethylenediimine nickel(II) (AA(2)enNi) 5%, [3] OV101 3% + bis (acetylacetone) propylene diimine nickel(II) (AA(2)PnNi) 5% [4] OV101 3% + bis(acetylacetone) meso-stilbenediimine nickel(II) (meso-AA(2)S Ni) 5% on Chromosorb G/NAW 60-80 mesh size have been calculated. The donor-acceptor complexation in gas phase is indicated with negative values of enthalpy, entropy and Gibbs' free energy.
