摘要：

The electron affinities (EAs) for carbon disulfide in the literature cluster around two values, 0.895+/-0.02 eV and 0.55+/-0.06 eV, Two negative ion states are observed in the temperature dependence of the electron-capture detector. The EAs obtained from these data are 0.61+/-0.04 eV for the linear anion and 0.873+/-0.025 eV for the bent anion. The theoretical semi-empirical MINDO/3 EAs are 0.582 eV and 0.891 eV. These support the literature values for the two states and establish the most appropriate values. (C) 1998 Elsevier Science B.V. All rights reserved.
