【摘要】 依据排列通道量子力学（ＡＣＱＭ）的基本原理，对分子离子ＨＤ＋的核间距和基态势能曲线以及离解能Ｄｅ做了理论计算，得到了ＨＤ＋的核间距为２．０７２５ａ０，并求得ＨＤ＋按两种方式离解时的势能曲线，认为多数ＨＤ＋应按Ｈ＋＋Ｄ的方式离解。通过比较计算，文章认为ＨＤ＋比更容易激发和离解，也更不稳定。同时文章对用ＡＣＱＭ解决非对称的同位素微团簇的一般方法做了简明阐述。更多还原

【Abstract】 In this paper, with the basic idea of arrangement -channel quantum mechanics(ACQM),We have calculated the internuclei separatiion of HD+molecular ion and its electronic dissociation energy, the values are 2. 0725ac, 2’ 9511eV respectively. Through calculation, we find that the dissociation of HD+ is easier than that of Hi, and H is more static than HD+ though the separation of HD+ is less than that of but its bond energy is lower.更多还原
