WebMar 25, 2016 · I'd like to point out that they are NOT standard notation. t-Bu stands for tert-butyl, i-Pr stands for isopropyl. These are just short hand abbreviations, mostly used in organic chemistry. They are not even abbreviations of standard, systematic names. Isopropyl, for example is a common name. WebThe concept of shielding will be explained shortly. The position on the plot at which the nuclei absorbs is called the chemical shift. Since this has an arbitrary value a standard reference point must be used. The two most common standards are TMS (tetramethylsilane, (Si (CH 3) 4) which has been assigned a chemical shift of zero, and CDCl 3 ...
