A free tool for the prediction of vicinal proton-proton 3J(HH) coupling constants. Download MestReJ. MestReS. A virtual NMR simulator package intended to allow students to learn and practice the NMR instrumental techniques while saving rather expensive spectrometer time and avoiding equipment damage due to improper use. the user can include the spectrum title (the title set previously on the spectrometer at acquire time) on any axis label by typing 't' in its corresponding edit box. >analysis >peak picking >manual threshold (or just type k) mnova can analyze and report multiplets in terms of chemical shift, splitting pattern, j-coupling (s), and of protons. … To calculate coupling constants in MestreNova, there are several options. The easiest one is to use the Multiplet Analysis tool. To do this, go to Analysis → Multiplet Analysis → Manual (or just hit the "J" key). Drag a box around each group of equivalent protons. How is J value calculated for Multiplet? Manual multiplet analysis: Press J, then click and drag to define the range and peak picking threshold for a multiplet. Multiplet Manager shows the properties of the current multiplet picked. (Double click on a multiplet label to open it) Multiplet label: Hover the cursor on it to see peaks. Use the bar to split a multiplet… Mnova 14 - SoftBooks - Mnova Manual Zoom in to defined ppm range Pan spectrum (or press P) ** Expansion -click&drag to draw an inset (or press E) Previous Zoom level Choose Multiplets, and check J's Tree to display the J-coupling tree for visual verification of the multiplet analysis results.
