In this paper,we Consider the π-electrons plaed in a one-dimenoisnal potential field with a cosine wave variation of ampllitude Vo along the chain and rising to infinty at the ends.The cosine potetial possesses the period in the sum of the C-C single bond and double bond distance. The crests and troughs of the cosine curve coincide with the longer and shorter bonds,respectively. The Schr(?)dinger equation satisfied with the boundary conditions,has been transformed to the Mathiu's equation expressed in terms of the same conditions with different forms.On the basis of solving the equation step by step,we have obtained the series expressions of the energy and the wave functions containing one paramater q.Through not too long calculation,the theoretical formulas for the wave number(8)and the oscillator strength of the maximum of the first absorbtion band(11)have been derived out. Good agreement with experimental results of polyenes and biphenyl polyenes for λ_1 and f_1 is obtained by the use of the above mentioned two equations.when q and α equal to zero,the equations(8)and(11)reduce to F E approximation very naturally.Applying this kind of zero order approximation,to the experimental deta of symmetrical polymethines have been given a good explanation as usual.
