论文摘要
虽然其振动基态的线性分子无法在其对称轴周围携带角动量，但振动激发的存在可以诱导远离线性的变形，因此也允许沿分子轴的角动量。在这项工作中，建立了复发关系，以计算线性分子的振动水平密度（状态的密度），该振动水平密度相对于能量和角动量指定。该关系应用于尺寸$ n = 4,6,7 $的碳簇作为案例研究。
While linear molecules in their vibrational ground state cannot carry angular momentum around their symmetry axis, the presence of vibrational excitations can induce deformations away from linearity and therefore also allow angular momentum along the molecular axis. In this work, a recurrence relation is established for the calculation of the vibrational level densities (densities of states) of linear molecules, specified with respect to both energy and angular momentum. The relation is applied to the carbon clusters of sizes $n=4,6,7$ as a case study.
