原子和分子的精确光谱学允许人们寻找基本常数的变化并对其施加严格的限制。这些实验通常用精细结构常数α和电子-质子质量比μ=me/mp的变化来解释。原子光谱通常对其他基本常数不太敏感，除非研究原子能级的超精细结构。然而，当允许常数的快速变化时，可能的无量纲常数的数量增加，其中“快速”由所研究的物种或所使用的实验装置的响应的时间尺度确定。在这种情况下，相关的无量纲量是，例如，比me/me和me是时间平均值。在这个意义上，可以说实验信号取决于量纲常数（在这个例子中是me）的变化。
Precision spectroscopy of atoms and molecules allows one to search for and to put stringent limits on the variation of fundamental constants. These experiments are typically interpreted in terms of variations of the fine structure constant α and the electron‐to‐proton mass ratio μ=me/mp . Atomic spectroscopy is usually less sensitive to other fundamental constants, unless the hyperfine structure of atomic levels is studied. However, the number of possible dimensionless constants increases when allowed for fast variations of the constants, where “fast” is determined by the time scale of the response of the studied species or experimental apparatus used. In this case, the relevant dimensionless quantity is, for example, the ratio me/⟨me⟩ and ⟨me⟩ is the time average. In this sense, one may say that the experimental signal depends on the variation of dimensionful constants ( me in this example).
