IR Spectra and Properties of Solid Acetone, an Interstellar and Cometary Molecule
Mid-infrared spectra of amorphous and crystalline acetone are presented along with measurements of the refractive index and density for both forms of the compound. Infrared band strengths are reported for the first time for amorphous and crystalline acetone, along with IR optical constants. Vapor pressures and a sublimation enthalpy for crystalline acetone also are reported. Positions of (sup 13) C-labeled acetone are measured. Band strengths are compared to gas-phase values and to the results of a density-functional calculation. A 73 percent error in previous work is identified and corrected.
