| Abstract: | Several 2-bromo-4′-substituted acetophenomes were investigated by vibrational and electronic spectroscopies. The solvent effect on the bands assigned to μCO and μC-Br together with the comparison between the fundamental and overtone μCO frequencies indicate a cis/gauche rotational isomerism. The progressive. |
