Abstract: ¹H and ¹³C chemical shifts of tert-butyl phenol compounds were determined by NMR. ¹³C-¹H one bond and long-range coupling constants (ⁿJ_COH). ¹³C-¹H gcminal coupling constants over the C-OH chain (²J_COH) and ¹³C-³¹P coupling constants (ⁿJ_CP) in It tert-butyl phenol compounds were obtained.
The coupling constants between aromatic hydrogen and aromatic carbon and the coupling constants between aromatic hydrogen (carbon) and aliphatic carbon (hydrogen) directly attached to aromatic are discussed. Induced and stcric effects on the coupling constants are also discussed.

Key words: Tert-butyl phenol compounds, ¹H & ¹³C NMR, Chemical shift, Coupling constant
