吡啶衍生物研究(Ⅰ)3-(4-吡啶基)-4-烷(芳)基-1,2,4-三唑啉-5-硫酮的NMR研究

NMR OF 3 (4 PYRIDYL) 4 ALKYL(ARYL) 1,2,4 TRIAZOLINE 5 THIONE

研究并归属了十七个３（４吡啶基）４烷（芳）基１，２，４三唑啉５硫酮的１ＨＮＭＲ和１３ＣＮＭＲ化学位移。

The 1H NMR and 13 C NMR chemical shifts of seventeen 3 (4 pyridyl) 4 alkyl(aryl) 1,2,4 triazoline 5 thiones were assigned. The main factors affecting chemical shifts were discussed.
