What are the limitations of the gNMR demo software?
Trial version restrictions and information about the release available for download. The trial version of gNMR is version 4.1. Unfortunately there is not a trial version of gNMR 5. The demo contains a fully functional version of the gNMR main simulation program, with only the following differences:....

Unable to install
I have clicked on the Install button on the opening splash screen but nothing happens. Because the ReadMe file contains important information regarding installation, the software is setup so that you need to click on the button to view this file, before it will allow you to install. gNMR 4.1 en....

System Requirements for gNMR
gNMR v4.1 requires an IBM compatible PC (at least a 486) running Windows 95/98 or Windows NT. 16Mb of memory & 10MB of disk space. gNMR 4.1 en....

How are the chemical shifts predicted?
I recently downloaded the gNMR demo version. I am curious as to how the chemical shifts are predicted because the predictions gNMR gave me for some simple model compounds were not even close to actual chemical shift values. Does the demo version use a limited chemical shift data base for its predi....

Importing structures/spectra into gNMR
Molecular structures from chemical drawing software can be imported via the clipboard from chemical drawing packages into gNMR for spectral simulation. Alternatively the structure can be imported as a file from the chemical drawing package. You can import structures from: 1. ChemIntosh (V3 (.ci3)....

Am I limited to exchange between equally populated sites?
I have a problem which consists of 4 processes: i) mol1 -> mol2 (exchanges sites 1-1 to 2-1 and 1-2 to 2-2 while 3-1 and 3-2 remain the same) ii) mol2 -> mol1 iii) mol2 -> mol3 iv) mol3 -> mol2. I cannot define the system like this in the exchange window. It looks like it accepts just one rate for ....

How many different NMR active nuclei is it aware of?
gNMR can cope with all NMR active nuclei, for example, if you have a molecule with carbon, boron and protons you will be able to display the splitting due to the boron and this can be either of the two isotopes or the natural abundance. gNMR is excellent for the simulation of all NMR active nuclei ....
