“…The process of digestion changes the valence state of Fe from Fe 2+ to Fe 3+ . The Fe 3+ ion located in the center of the porphyrin ring has a higher local symmetry than that found in hemoglobin and it is this higher symmetry that likely results in multiple absorption peaks at both higher and lower energies around the 285 eV peak similar to the symmetry peaks one finds in molecules such as dicoronene and benzopyrene (Butykai et al, 2013;Stö hr, 1992;de Groot, 2005;Tzvetkov et al, 2007;Desiraju & Gavezzotti, 1989).…”

Spectromicroscopy combines spectral data with microscopy, where typical datasets consist of a stack of images taken across a range of energies over a microscopic region of the sample. Manual analysis of these complex datasets can be time-consuming, and can miss the important traits in the data. With this in mind we have developed MANTiS, an open-source tool developed in Python for spectromicroscopy data analysis. The backbone of the package involves principal component analysis and cluster analysis, classifying pixels according to spectral similarity. Our goal is to provide a data analysis tool which is comprehensive, yet intuitive and easy to use. MANTiS is designed to lead the user through the analysis using story boards that describe each step in detail so that both experienced users and beginners are able to analyze their own data independently. These capabilities are illustrated through analysis of hard X-ray imaging of iron in Roman ceramics, and soft X-ray imaging of a malaria-infected red blood cell.

“…[30] As DNTT topologically consists of naphthalene and thiophene units, a comparison of the corresponding signatures is useful. Indeed, the NEXAFS spectrum of DNTT can be well-described by the NEXAFS signatures of these units, [42,43] as indicated by the dashed lines (blue: naphthalene-like resonance, orange: thiophene-like resonance, more details are given in Supp. Inf.).…”

octafluoro-dinaphthothienothiophene (F 8 DNTT) were synthesized via bisthiomethyl alkene intermediates which were accessible by McMurry coupling or Wittig olefination of partially fluorinated naphthalene precursors. DFT-based electronic structure calculations, near-edge X-ray absorption fine structure (NEXAFS) spectroscopy, and UV/Vis measurements were used for HOMO/LUMO gap determination and to analyze the electronic structures of the partially fluorinated DNTTs. Reduced exciton binding was observed in thin films.

“…This observation is well-supported by the optical gap, since both naphthalene and thiophene exhibit a much larger band gap than DNTT, which implies that DNTT consists of a fused π-system. Spectra of naphthalene and thiophene are taken from references [9][10].…”
