Effects of pH on the C-13 Magnetic Resonance Spectrum of Phenol

Volume 26, Number 2 (April 1972) Page 220-223

Nakashima, Thomas T.; Maciel, Gary E.


The C-13 chemical shift dependences of phenol on pH have been investigated and the shifts interpreted in terms of the phenol-phenoxide equilibrium and hydrogen bonding. In the low and high ranges of pH the carbon shifts have been related to subtle changes in the characteristics of solvent properties. The spectra were obtained using the Fourier transform technique.
