      The C NMR spectrum for 1-methylethyl propanoate 1-methylethyl propanoate is also known as isopropyl propanoate or isopropyl propionate. Here is the structure for 1-methylethyl propanoate: Two simple peaks There are two very simple peaks in the spectrum which could be identified easily from the second table above. The peak at is due to a 13 C NMR spectra, of diazido barbiturate it can be seen a signal at and ppm which corresponds to the carbon linked to the azide group, this signal is absent in all prepared polymers

    This book describes the use of NMR spectroscopy for dealing with problems of small organic molecule structural elucidation. It features a significant amount of vital chemical shift and coupling information but more importantly, it presents sound principles for the selection of the techniques relevant to the solving of particular types of problem, whilst stressing the importance of extracting   Welcome to WebSpectra - This site was established to provide chemistry students with a library of spectroscopy problems. Interpretation of spectra is a technique that requires practice - this site provides 1 H NMR and 13 C NMR, DEPT, COSY and IR spectra of various compounds for students to interpret. Hopefully, these problems will provide a useful resource to better understand ~webspectra.
