本文给出了一氯铝的两种同位素Al35Cl和Al37Cl2的谱线清单，其波长范围为0.2微米，JUP为400，适用温度为5000℃。线表是用经验光谱模型建立的，由势能曲线、自旋-轨道耦合曲线、电子角动量曲线和Born-Oppenheimer击穿修正曲线结合从头算偶极矩组成，涵盖了最低的四个电子态、、和。一些实验室振动谱的指认存在相当大的问题。讨论了处于连续体中的态的处理。可从ExoMol数据库www.exomol.com获得YNAT行列表。
A line list for two isotopologues of aluminium monochloride, Al35Cl and Al37Cl, is presented covering the wavelength range <0.2 µm,Jup to 400, and applicable for temperatures up to 5000 K. The line lists are built using an empirical spectroscopic model consisting of potential energy curves, spin–orbit coupling curves, electronic angular momentum curves, and Born–Oppenheimer breakdown correction curves combined with ab initio dipole moments and cover the four lowest electronic states,,,, and. Considerable problems with the assignments of some laboratory rovibronic spectra are identified. Treatment of the states lying in the continuum is discussed. The YNAT line list is available from the ExoMol data base at www.exomol.com.
