四甲基硫代四硫富瓦烯阳离子自由基的最长波长吸收带（通常被解释为π-二聚体带）被证明是本征阳离子自由基吸收，所有研究的阳离子自由基在室温下以顺磁性单体存在，并且只有四硫富瓦烯和四甲基四硫富瓦烯阳离子自由基在低温下经历π-二聚化。
The longest wave absorption band of the tetramethylthiotetrathiafulvalene cation radical, which is usually interpreted as a pi -dimer band, is shown to be the intrinsic cation radical absorption, all studied cation radicals in solution at room temperature exist as paramagnetic monomers and only tetrathiafulvelene and tetramethyltetrathiafulvalene cation radicals undergo pi -dimerization at low temperatures.
