Transformation NMR (FT-NMR). But time-domain based approaches such as the Bayesian statistics based CRAFT (Complete Reduction to Amplitude Frequency Table ) approach , allow the analysis of raw time-domain data and are the foundation of any subsequent interpretation and constitute the true raw data , while, at least in liquid NMR, only the frequency-domain spectra are directly accessible to visual and thus cognitive human interpretation. The interpretation of frequency-domain NMR spectra is associated with a set of terms that take a certain place in the connection between the nuclear spins, as the probed matter with certain physicochemical properties, and the NMR spectra as the corresponding humanreadable output.
