This app … WebThere are two types of such NMR, 1 H-NMR and 13 C-NMR. 1 H-NMR is the most commonly used NMR technique, and 13 C-NMR is rarely used. Unless you’re studying compounds with complex structures, you won’t use 13 C-NMR. In other words, you should only learn 1H-NMR at first. So, what is the principle behind 1 H-NMR?
WebFeb 25, 2024 · If you perform an 1 H, 13 C-HSQC you will find the 1JCH couplings, which means that the HSQC reveals which proton is directly bond to which carbon. Pretty useful, right? Like every other 2D NMR pulse sequence the one used for HSQC consists of three parts (figure 1). Preparation, evolution (t1) and mixing.
