I need help on HNMR analysis...
I found this HNMR spectra of lidocaine. Though i am aware of how HNMR works (the splitting of the peak corresponds to the number of neighbours...etc.) i am unsure of this particular spectra.
I know that the area under the peak = the no. of protons, chemical shifts is due to neighbouring atoms which have shielding or de-shielding effects and the no. of peaks corresponds to the no. of neighour proton around the particular proton.
Can someone give me an analysis of this spectra and how each peak corresponds to protons on lidocaine?
I have to acknowledge that i got the spectra from the UIC Chemistry Department HNMR facility website (http://www.chem.uic.edu/nmr/teaching_labs/index.html
