In the late 1930s, the best experimental value of the fine structure constant, α, was about 1/136.
The bias or odds can be estimated from an experimental value of the mean.
The question had been explored experimentally, but no theoretical treatment agreed with experimental values.
This value is two times lesser than the experimental value.
Initial measurements show very good agreement between experimental values and calculations based on quantum theory.
Thus, if an experimental value is less than the theoretical value, the percent error will be negative.
An experimental value should be used rather than one based on this approximation, where possible.
However, the experimental value of 26.3 significantly exceeds 24, and thus both pair sites might be occupied.
This value is in fairly close agreement with the experimental values measured by Allen, which are nevertheless generally 2 to 4 times higher.
This equation predicts a bond length which closer to the experimental value.
