“…However, far more common have been reports of just four or five 13 C signals resolved in the spectra of long‐chain n ‐alkanes: four 13 C signals for n ‐nonadecane ( n ‐C 19 H 40 , 19 ) in CCl 4 ; four 13 C signals for 20 neat or in CCl 4 ; five 13 C signals for 11 neat, in CDCl 3 , or in 4.1/0.8/5.1 v/v/v 11 /indan/CCl 4 ; five 13 C signals for 12 neat, in CHCl 2 CHCl 2 , in C 6 D 6 , or in 4.1/0.8/5.1 v/v/v 12 /indan/CCl 4 ; five 13 C signals for 13 neat; five 13 C signals for n ‐tetradecane ( n ‐C 14 H 30 , 14 ) neat or in CDCl 3 ; five 13 C signals for n ‐pentadecane ( n ‐C 15 H 32 , 15 ) neat 13 or in CDCl 3 ; five 13 C signals for 16 neat, in CDCl 3 , or in 4.1/0.8/5.1 v/v/v 16 /indan/CCl 4 ; five 13 C signals for 17 in CDCl 3 ; five 13 C signals for 18 neat, in CCl 4 , in 4.1/0.8/5.1 v/v/v 18 /indan/CCl 4 , or in 1‐chloronaphthalene; five 13 C signals for 19 in CDCl 3 ; five 13 C signals for 20 neat, in CDCl 3 , in CCl 4 , or in 1‐chloronaphthalene; and five 13 C signals for n ‐docosane ( n ‐C 22 H 46 , 22 ) in CDCl 3 . Thus, one could reasonably infer from the 1986 report of at least partial resolution of the ten different 13 C signals of 20 in 10/90 v/v C 6 D 6 /1‐chloronaphthalene at just 9.4 T (100.56 MHz 13 C) that this mixed solvent, rather than either of the individual solvent components, and a field strength higher than those used to study 20 in 1‐chloronaphthalene (20.09 MHz 13 C) or 18 in C 6 D 6 (67.8 MHz 13 C) are required to achieve such resolution.…”
