How do I calculate the 1 proton Chemical shift for the hydrogen forming a phenol for the attached compound? I have this book, Introduction to Spectroscopy by Donald L. Pavia. In table A6.1 the constant value for a hydrogen bonded to an oxygen is 2.56 and 1.85 for a mon. sub. benzene ring, but this is a disubstituted ring, I am not sure of the proper constant when the formula for the ring is C6H4 and and not C6H5.
