13C NMR Signal and Chemical Shift tural abundance of the ich is 99.985% of hydrogen Sassi The isotope 18C is another NMR active nucleus. The natural abundance isotope is only 1.1% of carbon atoms compared to the 'H isotope which is 99.985% of atoms. Therefore the intensity of WC peaks is lower. It takes a longer time to obtain a spectrum compared to a 'H NMR spectrum. Adjacent WC - WC splitting does occur. chance of two "C atoms being...

Based on the molecular formula and the UN/DBE you calculated, check all the functional group that could be present in compound B? Examine the IR spectrum provided for Compound B. The peaks below 1500 cannot be used to make any structural assignments because they are i fingerprint region. There are the two important peaks in this IR spectrum, What is each peak most likely due to? Earlier, using the molecular formula and the UN/BE, you came up...
