Spectre noesy
WebNMR spectroscopy is certainly the analytical methodology that provides the most information about a molecule. Teaching and interpreting spectra may however be challenging. On this webpage we have compile many tools that allows to: Predict 1D 1 H NMR spectra Predict 1D 13 C NMR spectra Predict COSY spectra Predict HSQC / HMBC … WebAprès une étude de faisabilité, le spectre 1H est attribué à partir d'une série d'expériences de RMN-2D : COSY, TOCSY, NOESY, ROESY, 13C-HSQC, 13C-HSQC-TOCSY qui ne nécessitent pas un marquage isotopique. Il est nécessaire pour cette étude de pouvoir atteindre des concentrations de l'ordre du 1mM.
