论文摘要
我们报告了对氢分子的两个同位素同位素学中超细相互作用的理论研究结果：H $ _ {2} $和D $ _ {2} $。我们提供了一组超精细耦合常数：自旋旋转，自旋旋转偶极子，在D $ _ {2} $分子的情况下，将在其地面电子$ x^{1}σ^{+stant = {+stant felectry Quadrupole耦合常数用于两个同位素的所有界面。我们提供了220 997个超精细分量的位置和强度列表，该成分为16 079 ROVIBLATITATION四极转变，O，Q和S分支。对于可靠的解释，对h $ _ {2} $和D $ _ {2} $的精确测量的可靠测量的可靠测量，必须使用超精细分量的位置和强度，这是用于分子量子动力学的测试，并在标准模型之外寻找新物理学的量子。
We report results of a theoretical investigation of hyperfine interactions in two homonuclear isotopologues of the hydrogen molecule: H$_{2}$ and D$_{2}$. We present a set of hyperfine coupling constants: spin-rotation, spin-spin dipole and, in the case of the D$_{2}$ molecule, electric quadrupole coupling constants for all bound states of the two isotopologues in their ground electronic $X^{1}Σ^{+}_{g}$ state. We provide a list of positions and intensities of 220 997 hyperfine components of 16 079 rovibrational quadrupole transitions of the O, Q and S branches. The positions and intensities of the hyperfine components are necessary for a reliable interpretation of accurate measurements of rovibrational transition frequencies in H$_{2}$ and D$_{2}$, which are used for tests of the quantum electrodynamics of molecules and searches for new physics beyond the Standard Model.
