我们更新了由 Millar、Herbst & Bettens 开发的 IRC 1 10216 化学模型，以包括最近形成硫化碳氢化合物的路线。这些路线基于 S 1 C 2 H 系统的量子化学研究。此外，我们还改变了硫的母体物种以反映新的观测结果。我们发现模型计算与观测到的柱密度非常吻合，并讨论了这些反应对尚未观测到的物种形成和暗星际云的重要性。
We have updated the chemical model of IRC 1 10216 developed by Millar, Herbst & Bettens to include recent routes to the formation of sulphuretted hydrocarbons. The routes are based on a quantum chemical study of the S 1 C 2 H system. In addition, we have altered the parent species for sulphur to reflect new observational results. We find that the model calculations give excellent agreement with the observed column densities, and discuss the significance of these reactions to the formation of species as yet unobserved and to dark interstellar clouds.
