## oscillator strength, $$f_{ij}$$

https://doi.org/10.1351/goldbook.O04339
Measure for integrated intensity of electronic transitions and related to the @E01914@ transition @P04855@ @C01124@ $$A_{ij}$$ by: $f_{ij} = 1.4992\times 10^{-14}\ \frac{A_{ij}}{s^{-1}}\ (\frac{\lambda }{\text{nm}})^{2}$ where $$\lambda$$ is the transition @W06659@. There are, however, differing uses of $$f$$.
