Infrared spectra for the vapor, liquid, and solid states of iodoacetone, and for solutions of iodoacetone were obtained. There are two rotational isomers present in approximately equal concentrations in the liquid state, but the less polar form is present in excess in the vapor. The more polar form is present in excess in the solid. Assignment of some of the fundamentals was made.
