MestReC Download Free Version
MestReC is no longer supported. There are so many new features and improvements in Mnova compared to MestReC that selecting the most relevant ones is not as easy as I had initially thought. If you want to print your spectrum from Mestrec you may first want to add text. Those who are not accustomed with this type of platform can turn to the extensive help file included in the application. Experiment with the exponential function.
If MestRe-C does not automatically recognize yoru fid, click the appropriate format, i. When you have finished manipulating your spectrum you may want to paste it into a Word document or print it out on its own. If you make a mistake and want to start phasing over, click Reset. However, MestRe-C Lite facilitates the delivery of the tools necessary for analyzing information and can be an extremely valuable asset that saves time and improves productivity.
Repeat this for all the peaks. We can interactively see the results of the window function on the fid by looking at the Fourier Transform in real time. Note that increasing the linewidth results in a broader, more featureless spectrum. Solvent suppression helps improve the appearance of the spectrum.
Measuring coupling constants. Click and hold the up or down arrows next to the Exponential Hz box.
You can choose another frequency by clicking and dragging in the spectrum. With the aid of the Integration module, users will be able to approximate the number of species inside the given spectrum. The coupling constant in automatically calculated. Click Invert, Quadrature, and Drift Correction.
These spins show no J-coupling and are separated by Hz. The manual baseline correction can also be used for greater control. This function is very useful for magnitude spectra because it reduces the dispersive part of the line shape. Next Article How to install and uninstall Mnova. The integral should now be gone.
Sine squared multiplication. Simulating simple systems.
You will see the decaying exponential that is your fid. In this screen you can reduce the size of your spectrum that is to be printed.
MestReC (free version) download for PC
Draw your molecule in Mnova or in any other molecular drawing package i. And if none of them fulfils your requirements, you can create your own customized multiplet report style. Interactive Apodization is not available. Of course, if you are a Windows User, having the ability to run the software in other platforms would not give you, apparently, any benefit.
To enlarge a portion of the spectrum, choose the magnifying glass on the toolbar. Experiment with the following window functions to see their affect on the fid. Once the information has been loaded, possibilities start to emerge as you navigate the menus and the quick toolbars embedded inside the main window.
The frequency intensity at A is now three times greater than B. To make integrals bigger or smaller use the up and down arrow keys on the keyboard. There are many different apodization, or window functions, you can apply to the fid.
After familiarizing yourself with the weighting functions, make the following further adjustments to the spectra. Note also that Mnova includes a peaks classification algorithm which helps to distinguish peaks according to their origin solvents, compound, artifacts, etc. Time This function is very useful for magnitude spectra because it reduces the dispersive part of the line shape. Co-founder and President of Mestrelab Research S. To paste it into a Word document go to the Edit menu and choose Copy.
If this does not work choose the next option on the Baseline Correction menu, i. When you click on this peak a box will appear with a list of reference values. The box, which appears, gives instructions as to what to do.
There are a number of Display Properties and Scale Properties that can be changed. Do you need to do any custom processing or analysis?
When you want to print go to the File menu and choose Print. All these requirements are possible in Mnova through its scripting and layout templates capabilities. Additionally, they can take a lot of time to get the job done. Open your fid using Mestre-C. To exit the peak picking option, delta software click on the tool again.
You can also apply peak picking to local maximas in order to make estimations on maximum values and furthermore, to estimate peak frequency. Manipulating the spectrum. Compare this predicted spectrum with the experimental one if available. Click Close to close this window.
Choose Close to get out of the print preview. If the peaks are too broad, resolution disappears, and only one peak can be detected. If you only want to delete one integral then deselect the Integration icon on the tool bar it has a picture of an integrated peak on it.
To integrate a peak hold down the left mouse button and drag the cursor over the peak and then let go the mouse button. You can simulate spins in a spectrum. To check what your spectrum will look like when you print it go to the File menu and choose Print Preview. Processing involves mathematical manipulation of the fid into the final Fourier transformed result. To integrate the peaks go to the Tools menu and highlight Integration.
Line fitting deconvolution required to analyze e. Click Full to return to the full spectrum.
Set spectral width to be Hz. Phase-shifted sinebell, or cosine bell. The following exercise demonstrates the difference in weighting functions and their effects on a spectrum. From the Process menu go to Baseline Correction and choose two-point baseline correction.
