Decomposition of Powder ESR Spectra: Ge-Centers in Natural Quartz

摘要

Fitting spectral contours on the basis of the set of separate paramagnetic centers is an effective procedure for decomposition of poly-component powder ESR spectra with strong overlapping of the lines of several centers (S=l/2). Let a spectrum represented as an n-dimensional vector Z be the sum of m spectral components determined as a vector basis X_i: Z = k_1X_1 + k_2X_2 + ... + k_mX_m.
