Imine compounds usually show stretching bands in the IR in the range of 1690-1649cm-1 and aromatic amines show a C-N stretch at 1340-1265cm-1. A related compound, N-benzylideneaniline, does not show tautomerism and has a C-N stretch at 1678cm-1 while H2SB-1(2-(2-hydroxybenzylideneamino)phenol ) shows a C-N stretch of 1590 cm-1. Given this information, does H2SB-1 show some C-N single bond character.
