描述了一组四重态有机苯基硝基自由基的低温、基质隔离 ESR 和电子光谱，使用硝酰基氮氧、苯并硝基氮氧和 verdazyl 自由基自旋位点以及间位和对位连接。从计算结果来看，对位连接系列中氮宾单元的离域并不广泛。 ESR 光谱结果表明，零场分裂更多地受到系统中连接性（对位与间位）的影响，而不是氮自由基主题内结构变化的影响。
The cryogenic, matrix-isolated ESR and electronic spectroscopy of a set of quartet state organic phenylnitreno-radicals are described, using nitronylnitroxide, benzo-nitronylnitroxide, and verdazyl radical spin sites, and both meta and para connectivities. Delocalization of the nitrene unit in the para-linked series is not extensive, judging by the computational results. The ESR spectral results show that zero-field splitting is affected much more by the connectivity in the systems (para versus meta) than by structural variations within the nitreno-radical theme.
