在氘和氚的巴耳末-α线的组件的波长已被确定在86氪606 nm的主要标准，以建立一个值的里德伯常数。通过使用液氦冷却的放电来减小多普勒宽度，从而提高了精细结构的分辨率。通过对谱线轮廓的分析，发现了精细结构成分的位置和强度。放电条件的变化没有产生与斯塔克效应理论预测相关的影响。氚的精细结构与氘的精细结构相同，在实验误差范围内，同位素位移可以用约化质量因子满意地描述。里德堡常数的值被发现是Rinfinity =109 737.326+或-0.008 cm-1。估计误差应理解为一个标准差。结果是基于氘精细结构中三个最强组分的测量。
The wavelengths of components of the Balmer- alpha line in dueterium and tritium have been determined in terms of the 86Kr 606 nm primary standard to establish a value for the Rydberg constant. Improved resolution of the fine structure was achieved by using a discharge cooled in liquid helium to reduce the Doppler width. Positions and intensities of the fine structure components were found by analysis of the spectral line profiles. Variation of the discharge conditions produced no effects which could be correlated with predictions of Stark effect theory. The fine structure of tritium was found to be the same as that of deuterium to within experimental error and the isotope shift was satisfactorily described by the reduced mass factor. The value of the Rydberg constant was found to be Rinfinity =109 737.326+or-0.008 cm-1. The estimated error is to be understood as one standard deviation. The result is based on measurements of the three strongest components in the deuterium fine structure.
