Analyzing NMR spectra with the Morlet wavelet
Aimamorn Suvichakorn, Jean-Pierre Antoine · 2008
The time-scale representation of the Morlet wavelet trans- form is studied on characterizing NMR signals. By an an- alytical analysis and simulations, the wavelet shows a satis- factory performance even when a baseline, an additive Gaussian noise and a solvent are presented in the signals. It can also cope with non-Lorentzian lineshapes which commonly occur due to inhomogeneous distribution of molecules in a substance. These results signify the Morlet wavelet transform as a potential tool to quantify in vivo NMR signals.
