Dear Rajaram

Only NMR will not lead you to the actual structure of the compound. You will need the FTIR and Mass spectra also which will help you to correlate the NMR data with the functional groups (FTIR) and the fragmentation patterns and molecular weight (Mass) of the isolated compound in question.

Thank you

Try Bruker CMC-se software

Dear friend!

Of course you should stick in your mind there is no software which interpret your NMR spectra and softwares are presented, they are only tools for viewing NMR spectra more carefully to extract more data of them. Structure elucidation of compounds needs at first understanding bases of magnetic resonance imaging and then knowing priority of compounds which may exist as your pure compound that NMR spectra have been provided of them. Third, searching basic characteristics of a special skeleton that you think your compound belong to that group and if there are not special NMR characteristics of that group, the presence of that skeleton would be ruled out. Of course you should remember for ever if you don’t know anything about priority of compounds may you have as pure compound, it’s similar to searching sand in a desert. However, if you have provided NMR spectra you can use “MestRec” free software. You can search MestRec free download in google and download and use that. I really would be glad to help you in interpreting your spectra based on my experiences.

Thank you

Software from two vendors ACDLabs and MestreLabs has verification capability where you can get reasonable answers by providing the spectra 1D/2D as well as a potential structure - you have to provide the structure you expect. They also have spectral prediction where you can see how your potential structure lines up with your spectra. Also if you have 13C data you can see the closest "spectral matches" by using CSEARCH (provided by Modgraph). At the end of the day you still have to have half a clue as to what you have as none of the tools can take data and simply spit out the molecule that it represents.

Thank you

I dont understand exactly your question . There is several sequence in 1D and 2D NMR spectroscopy available to elucidate a structure. If our question is related to the methodology that you have to use to elucidate the structure of a molecule . Of course

you can begin first by the 1H NMR proton followed by the COSY and HSQC experiment and then HMBC experiment to confirm your structure and if you have to determine the stereochemistry of some chiral centers present in your molecule you can use NOESY or ROESY experiments . In ID NMR sequence you may also use in this case NOE difference experiment.

You can also use marvin sketch software to interpret your NMR spectra. 

Thank you
