Features of the I.R. and U.V. spectra of seven C-aroyl derivatives of 2-phenacylpyridine are reported. Three of these derivatives form two solid isomers, and these are shown to be the cis OH/Py and trans OH/Py isomers of the enolic form. The remaining four compounds yield only one isomer and this is shown to be the trans OH/Py in each case.
