A series of ethyl N-substituted carbamates was synthesized by the reaction of ethyl chlorocarbamate with the appropriate amines. These chemicals were evaluated for repellent activity to mosquitoes (Aedes aegypti L.) on the treated backs of guinea pigs. The results indicated that among the N-monosubstituted compounds tested the ethyl N-(2-furyl) carbamate was most active, but in N,N-disubstituted carbamates the ethyl N-phenyl N-formyl carbamate was superior.A rough linear relationship between partition coefficient...

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.

本文采用的方法是,在一维方势籍中,引人周期为单键与双键长度之和的余弦型势函数。将适合附加条件的薛定谔方程经过变换,化成适合边界条件的马蒂安方程,利用逐步求解法,得出包含一个参数 q 的能量及波函数的级数表达式。经过一些计算,便推导出第一吸收峰的波数公式(9)和振子强度的理论公式(11)。应用这两个公式解释多烯烃及双苯基多烯烃的光谱时,结果还比较满意,利用这种近似,也解释了不对称的聚甲川分子的实验数据。当 q=0,α=0,时,非常自然地推导出简单自由电子理论公式,满意地解释了对称聚甲川分子的实验数据。根据自由电子模型,对维特经典色泽理论的结果,也在文中示例予以阐明。
