Abstract
Splitting parameters measured in the sensitive 31P part of an AA′XX′ 31P–103Rh spectrum make it possible to perform a multiplet-matched digital filtering of the weak 103Rh 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.
