I'm just starting to learn a little bit about NMR. I want to know if the result or peaks obtained with NMR is compared with the existing database like XRD to identify the molecular, structure or type of compound?
Is it very specific like XRD and HPLC or is it not that strict and followed a range identification like FTIR spectroscopy?
I'm sorry if my English is confusing...
Comparing your NMR spectrum with database is certainly possible, but it is much more common (and critically important for chemists) to be able to analyze and interpret your own experimental NMR data.
NMR is like "eyes" for organic chemists, you won't be able to work in organic chemistry field without good understanding of various aspects of NMR.
Thank you, I'm just starting to learn a bit about it and still needs a lot of reading for better understanding.
Hello, one can predict the NMR spectroscopy values by basic understanding of chemical environment present around the proton or carbon that is under study.
For the comparison of values one can use Scifinder structure search tools, if the compound is already known in the literature, scifinder search gives relatively better values.
The simplest way to predict the values of the compound under study is by chemdraw (although the all values are not accurate)
I agree with the previous comment and would also underline the primary importance of NMR tecniques in Natural Product Chemistry. In this context you may compare the experimental data with those in literature when you analyze a known compound but you must interpret the obtained data if the compound was not previously described.
