Abstract
1H chemical shift assignments are presented for 2‐methyladamantane, 2‐methylnorbornane (endo and exo) and 2‐methylnorbornene (endo and exo). Resonance assignment was achieved using a variety of 1D and 2D homo‐ and heteronuclear (1H–13C) experiments. The methyl group‐induced substituent chemical shift (SCS) is derived and the SCS of protons vicinal to this group is discussed.Keywords
