研究了具有取代基的链式分子的有效电子-电子相互作用。所考虑的体系分为两部分：主链称为脊链和取代基，在我们的情况下是侧链。在估计脊状结构中有效电子-电子相互作用时，同时考虑了脊状结构和侧链产生的极化效应。因此，所得到的公式是相当一般的，因此目前的处理被当作特殊的处理来再现。有几个例子是用数值处理的。结果表明，从有效相互作用的角度来看，利特尔的想法，即室温有机超导体是不可能的。
Effective electron-electron interactions are investigated in chain molecules with substituents. The 'system under consideration is divided into two parts: the main chain called the spine and the substituents which are side chains in our case. In estimating the effective electron electron interaction in the spine, the polarization effects arising from the spine and the side chains are both taken into account. The resultant formula, thus, is rather general, so that the current treatments are reproduced as special ones. A few examples are treated numerical,ly. Results indicate that Little's idea, namely the room temperature organic superconductor is unlikely from the viewpoint of the effective interaction.
