Using an atomic absorption spectrophotometer to analyze several hairs from Baker's head, Ray A. Neff, a professor at Indiana State University, determined the man was killed by arsenic poisoning rather than meningitis.

As an approximation, the conjugated backbone can be considered as a real-world example of the "electron-in-a-box" solution to the Schrödinger equation; however, the development of refined models to accurately predict absorption and fluorescence spectra of well-defined oligo(thiophene) systems is ongoing.
