The magnetic field dependence of the FT ESEEM spectra obtained by dividing time domain ESEEM collected for the TauD samples treated with α-KG and C1-2H-taurine by identical data for the TauD samples treated with α-KG and 1H-taurine. Each plot is labeled with the field position at which the data were collected. The Hamiltonian parameters used to calculate the (blue) lines were: hyperfine coupling values of −0.21, −0.21, and 0.42 MHz; Euler angles for the hyperfine tensor of 0°, 26°, and 0°; e2qQ/h = 0.22 MHz and η=0; Euler angles for the nuclear quadrupole tensor of 0°, 52°, and 25°.
