TSAR: a program for automatic resonance assignment using 2D cross-sections of high dimensionality, high-resolution spectra
TSAR: a program for automatic resonance assignment using 2D cross-sections of high dimensionality, high-resolution spectra
Abstract While NMR studies of proteins typically aim at structure, dynamics or interactions, resonance assignments represent in almost all cases the initial step of the analysis. With increasing complexity of the NMR spectra, for example due to decreasing extent of ordered structure, this task often becomes both difficult and time-consuming, and the recording of high-dimensional data with high-resolution may be essential. Random sampling of the evolution time space,...

[Question from NMRWiki Q&A forum] software for 1D-2D spectra assignment for small molecules
software for 1D-2D spectra assignment for small molecules
Please advice good software for 1D and 2D spectra assignment and structure elucidation,for small organic molecules.I'm really tired of doing these assignments on printed-out spectra with color pencils.
Check if somebody has answered this question on NMRWiki QA forum
