Proton and carbon NMR analyses are routinely used in organic laboratories. In proton, 1H-1H coupling pattern is well exploited, and 1H-13C couplings as referred to as the carbon satellites. However, when acquiring carbon data, proton decoupling is applied most of the time and consequently it is not common to evaluate 1H-13C couplings in routine carbon analysis. This blog discusses the 1H-13C coupling in tert-butanol through 1D and 2D data, highlighting the key info. Read more.
