采用w - esr光谱法测定了254 nm和365 nm紫外光照射下N@ C60在5种溶剂中的光诱导分解。结果表明，N@ C60的分解速率与溶剂的选择有很大关系。研究结果表明，二硫化碳和顺/转十萘是未来N@ C60光激发实验中最合适的溶剂。此外，对比了N@ C60在环境溶剂和脱气溶剂中的衰变速率，表明分解主要不是通过3C60激发态和氮原子的相互作用进行的。
Using CW-ESR spectroscopy, the photo induced decomposition of N@ C60 in five solvents under irradiation with 254 nm and 365 nm ultra violet light was measured. The results indicate that the decomposition rate of N@ C60 is highly dependent on the solvent chosen. The finding shows that carbon disulphide and cis/transdecalin are the most suitable solvents for future photoexitation experiments of N@ C60. In addition a comparison between decay rate of N@ C60 in ambient and degassed solvents suggests that decomposition is not principally via an interaction of the 3C60 excited state and the nitrogen atom.
