四硅螺二茚满阴离子自由基（1-）的ESR谱在低温下表现为双峰的hfs谱，且谱线宽度有明显的变化，表明苯环上两个带未成对电子的硅取代基之间受电子效应的显著差异是由环的构象决定的.
ESR spectra of a tetrasilaspirobiindane anion radical (1−) showed a doublet of doublet hfs pattern at low temperatures and significant line-width alternation, indicating that there is remarkable difference in the electron-accepting effects between two silyl substituents at the benzene ring with the unpaired electron due to the ring conformation.
