Chemistry question on NMR Spectroscopy?
What exactly does "proton shielding", chemical shifts and exterior magnetic field in respect to NMR mean? What are the trends in the chemical shift? Is it the higher the shift, the lower the proton shielding, thus it is easier for them to "flip", or is it the other way around? And what does "resonance" mean?Thanks for your inspiring explanations, which I understood fairly well.
