We present a method of simulating the EPR spectra of spin labels in liquids using direct
convolution of hyperfine splitting with Lorentzian linewidths. The aim is to simulate the
experimental lineshape by considering all spectrometer characteristics as well as
inhomogeneous and homogenous linewidth effects. A major advance in this method is the
correction for the broadening produced by Zeeman modulation commonly used to obtain
EPR signals; this allows experimenters much more freedom to optimize their experimental …
