The molar absorptivity (molar extinction coefficient) E is defined as E = Aλ • mol−1 • 1 • cm−1, where Aλ is the absorbance at the wavelength λ and mol • 1−1 refers to the molar concentration of polymeric or oligomeric phosphorus or base (this may be indicated in the Note column by letters P and B, respectively) and cm to the light path. Some Eλ values of oligomers are given as absorbance per 1 mol of oligomer; such values are underscored. Whenever possible, Eλ values are given for each listed compound together with hypochromicity or hyperchromicity data. Only in cases of uncommon derivatives are references included that give incomplete data (e.g., λmax).
