The Wigner–Seitz model for a core–core cutoff pseudopotential introduced by Springett et al. is used to predict effective masses of quasifree electrons in inert gas solids. The model has been useful in predicting or correlating ground state energies of electrons in liquid (Springett et al., Raz and Jortner, and Miyakawa and Dexter) and solid (Raz and Jortner) inert gases. The theoretical effective masses reported herein are at least a factor of two too high, even for Ne for which the model gives a good a priori prediction for the ground state quasifree electronic energy. The failure of the model in predicting excited state properties (namely, the effective masses) brings into question Miyakawa and Dexter's use of the potential barrier (Springett el al.) predicted by the same model in treating photoexcitation of electronic bubbles in liquid helium.

The phenomenon of bioluminescence has fascinated layman and scientist alike for many centuries. During the eighteenth and nineteenth centuries a number of observations were reported on the physiology of bioluminescence in Renilla, the common sea pansy. More recently biochemists have directed their attention to the molecular basis of luminosity in this colonial form. These studies have centered primarily on defining the chemical basis for bioluminescence and its control. It is now established that bioluminescence in Renilla arises due to the luciferase-catalyzed oxidation of luciferin. This results in the creation of a product (oxyluciferin) in an electronic excited state. The transition of oxyluciferin from its excited state to the ground state leads to light emission.

Core edge spectroscopy methods are versatile tools for investigating a wide variety of materials. They can be used to probe the electronic states of materials in bulk solids, on surfaces, or in the gas phase. This family of methods involves promoting an inner shell (core) electron to an excited state and recording either the primary excitation or secondary decay of the excited state. The techniques are complimentary and have different strengths and limitations for studying challenging aspects of materials. The need to identify components in polymers or polymer blends at high spatial resolution has driven development, application, and integration of results from several of these methods.

In this work, ground and excited-state properties were used as descriptors for probing mechanisms as well as to assess potential alternatives for tackling the elimination of per- and poly-fluoroalkyl substances (PFAS).
