| We have begun an investigation of how meta and para substitution of various groups in phenols affects the frequency of both free and hydrogen bonded O-H stretching bands. Preliminary results suggest that the electron-withdrawing or electron-releasing nature of the substituent group does have a measurable effect on the O-H stretching band, even in the para position. Electron releasing groups such as methyl appear to increase the frequency of the O-H stretching band while the electron withdrawing groups seem to decrease the frequency of the O-H stretching band. Compounds under investigation include a variety of halo and methyl substituted phenols. |
