Concept explainers
Interpretation:
The 13CNMR spectrum of homotropilidene taken at room temperature shows three peaks.
Concept introduction:
Carbon-13 (C13) nuclear magnetic resonance (most commonly known as carbon-13 NMR or 13C NMR or sometimes simply referred to as carbon NMR) is the application of nuclear magnetic resonance (NMR) spectroscopy to carbon. It is analogous to proton NMR (1HNMR) and allows the identification of carbon atoms in an organic molecule just as proton NMR identifies hydrogen atoms. As such 13CNMR is an important tool in chemical structure elucidation in organic chemistry. 13CNMR detects only the 13C isotope of carbon, whose
13C chemical shifts follow the same principles as those of 1H, although the typical range of chemical shifts is much larger than for 1H.
