Frequently the chemical shifts (Table 2.3) of molecular fragments and functional groups containing nitrogen complement their 77and C shifts. The ammonia scale of N shifts used in Table 2.3 shows very obvious parallels with the TMS scale of C shifts. Thus, the N shifts (Table 2.3) decrease in size in the sequence nitroso, nitro, imino, amino, following the corresponding behaviour of the C shifts of carbonyl, carboxy, alkenyl and alkyl carbon atoms (Table 2.2). [Pg.143]

Table 3. Name and structure of organic functional groups containing nitrogen and oxygen. Table 3. Name and structure of organic functional groups containing nitrogen and oxygen.
The functional groups — NFU, —NO and —NO2 contain atoms which have the following naturally occurring NMR active nucleides 1H, 2H, 14N, 15N and 170. Table 1 lists some of their basic NMR characteristics as well as those of the 13 C isotope of the carbon atom, which is invariably one of the atoms normally attached to nitrogen in the compounds discussed in this book. [Pg.296]
