The geometries of the anionic surfactants with different hydrophobic bases in gas and water were optimized using RHF/6-31G* and Onsager reaction field model, respectively. The total energies, net charges, dipole moments and polarization energies of the surface-active anions were obtained in gas and water. The characters of geometries and electronic structures for the surface-active anions in gas and water were compared. The effect of the different hydrophobic bases on the surface tension was also investigated.

Key words: anionic surfactant with different hydrophobic base, ab initio, Onsager model, surfactant tension
