Abstract
We present a simple approach to reconstruction of NUS 2D spectral series as used in relaxation analysis. The approach treats this data as an ordinary 3D time-domain measurement whose imaginary part in the pseudo-dimension is zero, with familiar 3D NUS reconstruction methods such as IST applied accordingly. Best results on measured and simulated data were achieved using acquisitions with 9-to-12 planes and exponential spacing in the pseudo-dimension out to 2 times the inverse decay time. Given these criteria, the new approach can generate spectra reliably at sampling densities of 25% relative to a conventional measurement.Citation
