A new method for quantitative analysis of time-domain signals is reported. It amounts to fitting a function consisting of exponentially damped sinusoids with arbitrary phases to the data. By invoking the principle of linear prediction (LP) the fittin

Hyperfine interaction frequencies of 1H and 39K nuclei near the AsO4-4 radical in X-ray irradiated KH2AsO4 (KDA) have been observed through the method of electron spin echo envelope modulation (ESEEM). This method enabled us to record nuclear hyperfi

The accuracy of spin-Hamiltonian determination via analysis of electron spin-echo nuclear modulation signals is investigated for F centers in KCl. It turns out that the accuracy matches that of ENDOR. The linewidth of the signals converted to the fre

This communication is concerned with a new method of fitting a physical model function to a magnetic resonance signal, directly in the time domain. Our primary aim is analysis of the signal in quantitative terms, i.e., describing the signal in terms

A parametric spectral analysis based on linear prediction and singular value decomposition has been applied to the 31P FID of a tumor implanted in a mouse. It is found that a number of complications that may arise in in vivo FFT NMR can be circumvent

The existing theory of electron spin-echo envelope modulation (ESEEM) is extended to the case where a hyperfine manifold is excited only partially. The extension is important for application of ESEEM to analytical work. The theory has been worked out

The energy levels of the nucleus of a K+ ion near a paramagnetic Gd3+ ion, both substituted in CaF2, have been measured with the recently developed technique of electron spin echo envelope modulation, combined with an also recently developed microwav
