## Abstract The complete assignment of the high‐resolution NMR spectra 2,4‐dinitrofluorobenzene was made, including the ^1^H, ^13^C, ^15^N, ^17^O and ^19^F nuclei. The ^13^C,^19^F, ^13^C,^1^H, ^15^N,^19^F and ^15^N,^1^H one‐bond and long‐range coupling constants were determinated and the signs were

A series of 2'-fluorinated adenosine compounds, dAfl, dAflp, pdAfl, dAfl-A, A-dAfl, and dAfl-dAfl, have been investigated by nmr spectroscopies. The 'H-, I9F-, and 31P-nmr data provide structural information from different parts of these molecules. The pK, of the phosphate group of these two 2'-fluo
## Abstract ^1^H, ^13^C, ^14^N and ^15^N NMR chemical shifts were used to prove the structures of the products of 2‐chloropyrazine oxidation. It was shown that oxidation by hydrogen peroxide in acetic acid or __m__‐chloroperbenzoic acid leads to the __N__4‐oxide, whereas potassium persulfate in sul
## Abstract ^1^H and ^13^C NMR spectra are reported and assigned for imidazo[1,2‐__a__] pyrazine and for __N__‐1‐methyl‐ and __N__‐7‐methyl‐imidazo[1,2‐__a__] pyrazinium iodides. The effect of protonation on the chemical shifts of the parent molecule is demonstrated, and through the use of ^13^C an
The complete assignment of 19 F, 1 H and 13 C NMR spectra for a monosubstituted octafluoro[2.2]paracyclophane derivative is described for the first time. The unambiguous assignments were achieved through the combination of 19 F-1 H HOESY, 1 H COSY and 19 F COSY techniques and then further confirmed
## Abstract The ^1^H, ^13^C, and ^15^N NMR spectra of 5 exocyclic alkenes and 15 different ketimines obtained from cyclohexanone and derivatives using benzyl bromide and primary amines—are analyzed. Relative stereochemical and preferential conformations are determined by analyzing both the homonucl
