WebMar 8, 2024 · Recent developments in data sampling and processing techniques have made it possible to acquire 2‐dimensional NMR spectra of small molecules at digital resolutions in both dimensions approaching the intrinsic limitations of the equipment and sample on a realistic timescale. In signal processing, the coherence is a statistic that can be used to examine the relation between two signals or data sets. It is commonly used to estimate the power transfer between input and output of a linear system. If the signals are ergodic, and the system function is linear, it can be used to estimate the causality between the input and output. cloudformation guarddutyWebSep 16, 2008 · Coherence transfer involves transferring coherences or magnetization components between coupled spins, keeping track of the source and destination spin precession frequencies.
