Supplementary Material: In situ heating cell for temperature dependent transmission XAS measurement with a laboratory based spectrome

This is the supplementary material for the work with the title "In situ heating cell for temperature dependent transmission XAS measurement with a laboratory based spectrometer". It consists the pre-characterization of the used spin crossover complex [Fe(bzimpy)2](ClO4)2·0.25H2O in section I, which has been investigated and shows a spin transition when heated above room temperature. Section II is listing the temperature profiles (temperature set point Tset and actual measured temperature Tmeas ) of the heat cell for the shown in situ XAS measurements as well as of the current reached limits of the cell and the maximum heating ramp for on-the-fly measurments. In section III, the results of the in situ XAS measurements, conducted on the sample [Fe(bzimpy)2](ClO4)2·0.25H2O at a temperature up to 250{degree sign}C, are presented.
