我们希望通过获得更完整的化学物质的知识,更定量地了解致密云及其热核心的化学物质。我们已经获得了高分辨率的红外吸收光谱在3-4微米对明亮的红外光源CRL 2136。首次在浓云中探测到HCl的基本振动-旋转带。HCl可能位于CRL 2136温暖致密的星周包层或盘中。HCl的丰度分数为(4.9-8.7)e-8,表明约20%的元素氯存在于气态HCl中。吸收气体的动力学温度为250 K,是由13 CO和水的红外光谱测定的值的一半。HCl中氯的百分比与此温度下气体的预期百分比大致相同。各种分子种类之间温度差异的原因尚不清楚。
We would like to understand the chemistry of dense clouds and their hot cores more quantitatively by obtaining more complete knowledge of the chemical species present in them. We have obtained high-resolution infrared absorption spectroscopy at 3-4 um toward the bright infrared source CRL 2136. The fundamental vibration-rotation band of HCl has been detected within a dense cloud for the first time. The HCl is probably located in the warm compact circumstellar envelope or disk of CRL 2136. The fractional abundance of HCl is (4.9-8.7)e-8, indicating that approximately 20 % of the elemental chlorine is in gaseous HCl. The kinetic temperature of the absorbing gas is 250 K, half the value determined from infrared spectroscopy of 13CO and water. The percentage of chlorine in HCl is approximately that expected for gas at this temperature. The reason for the difference in temperatures between the various molecular species is unknown.
