Solvated electron: criticism of a suggested correlation of chemical potential with optical absorption energy

A recent theoretical treatment of the absorption spectrum of the solvated electron, e-sub(s), maintains that rigorously μ0 >= -0.75 Esub(av), which gives empirical relationship, μ0 >= -(0.93 +- 0.02)Esub(max). For e-sub(s) in a particular solvent at a temperature and pressure, μ0, Esub(av) and Esub(max) are standard chemical potential, average energy of the absorption spectrum and the energy at the absorption maximum respectively. The temperature and pressure effects on the absorption spectrum of e-sub(s) in water and liquid ammonia do not support the equality sign in the above cited relationships. The implications of inequality expressed above are discussed for e-sub(s) in water and liquid ammonia. (author)
