Abstract

All published to date experimental wavenumber values (ν, cm^–1) for electronic-vibro-rotational transitions of the H₂ molecule are statistically analyzed in the vacuum wavelength range 1/ν = 600—610 nm. It is shown that a direct comparison of all datasets of various authors is blocked by the absence of deconvolving of measured spectra, blending of neighbor lines (an overlap of their profiles), and fragmentary data of most studies. Therefore, it is proposed to compare all available data with the dispersion curve of a high-resolution spectrometer by measuring and deconvolving the H₂ spectra. An experimental study of such an opportunity showed that the proposed approach makes it possible not only to analyze the scatter of available data on 1/ν and ν (standard deviations are about 0.003 nm and 0.08 cm^–1), but also to obtain more reliable datasets with uncertainties (95% confidence intervals) less than 0.0006 nm and 0.02 cm^–1 respectively.

H 2分子的电子-振动-旋转跃迁的可用波数值的准确性

摘要

迄今为止，所有已发布的H ₂分子电子振动旋转跃迁的实验波数值（ν，cm ^–1）在真空波长范围1 /ν= 600-610 nm中进行统计分析。结果表明，对大多数作者的所有数据集进行的直接比较由于缺乏对测量光谱的去卷积，相邻线的混合（它们的轮廓的重叠）以及大多数研究的零碎数据的阻碍。因此，建议通过测量和解卷积H ₂将所有可用数据与高分辨率光谱仪的色散曲线进行比较。光谱。对这种机会的实验研究表明，所提出的方法不仅可以分析1 /ν和ν上的可用数据的散布（标准偏差约为0.003 nm和0.08 cm ^–1），而且可以获得更可靠的结果。不确定性（95％置信区间）分别小于0.0006 nm和0.02 cm ^–1的数据集。
