Multiplet-Matched Filtering of 103Rh Signal Using Information Contained in 31P Spectrum of AA′XX′ 31P–103Rh Spin System

Multiplet-Matched Filtering of 103Rh Signal Using Information Contained in 31P Spectrum of AA′XX′ 31P–103Rh Spin System

Splitting parameters measured in the sensitive 31 P part of an AA′XX′ 31 P– 103 Rh spectrum make it possible to perform a multiplet-matched digital filtering of the weak 103 Rh free induction decay signal. Compared to the conventional matched exponential weighting, this multiplet-matched filtering h...

Zusammenfassung:Splitting parameters measured in the sensitive 31 P part of an AA′XX′ 31 P– 103 Rh spectrum make it possible to perform a multiplet-matched digital filtering of the weak 103 Rh free induction decay signal. Compared to the conventional matched exponential weighting, this multiplet-matched filtering has provided a gain of 1.8 ± 0.4 in the signal-to-noise ratio of the experimental rhodium spectrum. The maximum gain predicted theoretically is equal to 2.
