Multiple electron affinities are identified in the temperature dependence of the electron-capture detector: naphthalene, 0.16, 0.13+/-0.01, anthracene, 0.69, 0.60, 0 53+/-0.01; tetracene 1.1, 0.88+/-0.03, 0.53+/-0.05; pyrene, 0.61, 0.50+/-0.02; azulene 0.90, 0.80, 0.70+/-0.02, 0.65, 0.55+/-0.05; acenaphthylene, 0.80, 0.69, 0.60, 0.50+/-0.05; and c-C8H8, 0.80, 0.70, 0.55+/-0.02; (all in eV). These are obtained from a rigorous least squares procedure incorporating literature values and uncertainties. The adiabatic electron affinities for about 40 hydrocarbons listed in the US National Institute of Standards and Technology (NIST) tables are evaluated. The adiabatic electron affinity values not listed in NIST are biphenylene, 0.45+/-0.05 eV and coronene. 0.8+/-0.05 eV. Morse potential energy curves in the C-H dimensions illustrate multiple states for benzene and naphthalene.
萘，0.16、0.13±0.01；蒽，0.69、0.60、0.53±0.01；并四苯，1.1、0.88±0.03、0.53±0.05；芘，0.61、0.50±0.02；薁，0.90、0.80、0.70±0.02、0.65、0.55±0.05；苊烯，0.80、0.69、0.60、0.50±0.05；以及环辛烷，0.80、0.70、0.55±0.02；（均以电子伏特为单位）。这些是通过结合文献值和不确定性的严格最小二乘法程序获得的。对美国国家标准与技术研究院（NIST）表格中列出的约40种碳氢化合物的绝热电子亲和势进行了评估。NIST未列出的绝热电子亲和势值有联苯撑，0.45±0.05电子伏特和 coronene，0.8±0.05电子伏特。C-H维度中的莫尔斯势能曲线说明了苯和萘的多个状态。
