我们结合了有限数量的精确测量的氢和氘的跃迁频率、最近的量子电动力学 (QED) 计算以及作为重要附加成分的广义最小二乘分析，以获得氢和氘跃迁频率的精确和最佳预测。一些预测的跃迁频率具有比电子 g 因子小一个数量级以上的相对不确定性，而电子 g 因子是之前 QED 最准确的预测。
We combine a limited number of accurately measured transition frequencies in hydrogen and deuterium, recent quantum electrodynamics (QED) calculations, and, as an essential additional ingredient, a generalized least-squares analysis, to obtain precise and optimal predictions for hydrogen and deuterium transition frequencies. Some of the predicted transition frequencies have relative uncertainties more than an order of magnitude smaller than that of the g factor of the electron, which was previously the most accurate prediction of QED.
