The spectrum of TaS between 4000 and 20 000 cm-1 has been recorded in emission from a microwave discharge with a resolution between 0.011 and 0.025 cm-1. Seventeen electronic transitions have been rotationally analyzed. Fifteen of these have the ground state, 2Delta, as the lower state and two of them are transitions between excited states. The ground state has been fitted to a Hund's case (a) Hamiltonian. Effective molecular constants have been determined for the excited states, which are mainly described as Hund's case (c). Perturbations that have been found in the excited states are discussed. Transitions between states that are connected neither to the ground state nor to any of the other 14 electronic states of this work have been found. No analysis is presented for these transitions, but some of their characteristic features are described. Copyright 1998 Academic Press.

TaS 在可见光和近红外区域的高分辨率光谱

4000 到 20 000 cm-1 之间的 TaS 光谱已记录在微波放电发射中，分辨率在 0.011 到 0.025 cm-1 之间。已经对 17 个电子跃迁进行了旋转分析。其中 15 个具有基态 2Delta，作为较低的状态，其中两个是激发态之间的跃迁。基态已经拟合到 Hund 的情况 (a) 哈密顿量。已确定激发态的有效分子常数，主要描述为 Hund 的情况 (c)。讨论了在激发态中发现的扰动。已经发现既不与基态也不与本工作的其他 14 种电子态中的任何一种相关的状态之间的转换。没有对这些转变进行分析，但描述了它们的一些特征。版权所有 1998 学术出版社。
