Inside Cover: Fourier Transform EPR Spectroscopy of Trityl Radicals for Multifunctional Assessment of Chemical Microenvironment (Angew. Chem. Int. Ed. 10/2014)
The long relaxation times of the monophosphonated trityl radical make possible its application in pulsed EPR spectroscopy. In their Communication on page 2735 ff., V. V. Khramtsov et al. use Fourier transform EPR spectroscopy in combination with the trityl probe to assess the physiologically relevant parameters of a chemical microenvironment. The spectra analysis enables quantitative and discriminative assessment of pH, pO2, and the concentrations of inorganic phosphate (Pi) and probe.
