Abstract: The double-well potential model is very useful for describing proton transfer.And the curve pic-ture of the sextic function V(R, γ) =R6+2γR4 + (γ2+μ)R2 has a double-well form, when γ and μ satisfya specific conditions.So it can be used as the potential function of proton transfer by modification.Mostimportantly, its corresponding Schrdriinger equation has exact1y analytic solutions.Thus it shows its su-periority over the quartic one V(R) =A(R4-BR2) which has double-well form, but is not a solvable po-tential function.Based on the sextic function, the energy level splitting of the ground state of 9-hydrox-yphenalone was studied by using linear variational method.The obtained results is better compared withthe experimental ones.

Key words: Proton transfer, Tunneling effect, Energy level splitting, Solvable potential function
