“…In most of the relevant cases the triplets are distributed in some solvent or in a solid matrix. Therefore, we do not consider in our treatment g factor anisotropy or hyperfine terms, as they are seldom resolved in the inhomogenously broadened triplet spectra obtained for such cases (17). The case of single crystal spectra, where sharp lines are obtained, is unique in this respect (18).…”

ABSTRACT:We present a simple yet powerful method of simulating continuous wave electron spin resonance line shape of triplets in frozen and liquid solutions. The analysis enables one to consider cases such as immobilized triplets with random distribution, anisotropic slow and fast rotation of the triplet molecules, exchange between triplets with different Hamiltonians, anisotropic relaxation rates, and triplets with non-Boltzmann population distribution of the spin levels. Theoretical basis for the method is provided, along with several examples of simulated and experimental spectra for various physical conditions. A short "Matlab" routine, which can be used in the numerical spectra simulation, is given in the Appendix.

A procedure is developed to calculate pulsed electron paramagnetic resonance (EPR) signals with relaxation rigorously. It can be carried out within a reasonable time on a PC using Fortran or Matlab, not requiring any sophisticated software. The flow chart for this kind of simulation is included. It is illustrated here numerically, as coded in Matlab, to calculate the twodimensional spin echo correlation spectroscopy (2D-SECSY) and two-dimensional electron-electron double-resonance (2D-ELDOR) signals for two cases: (i) a coupled electron-nuclear system with the electron spin (S= ½) and nuclear spin (I= ½) corresponding to the experimental results of Lee, Patyal and Freed [1] in a malonic acid single crystal, and (ii) 2D-ELDOR signal obtained for an electron-electron dipolar-coupled system of two nitroxide radicals in a malonic acid single crystal, with hyperfine interactions included, for a proposed experiment, intended for distance measurements, important for biological systems. The limits of applicability of the algorithm used here are discussed.
