Acetyl chloride in an argon matrix decomposed on irradiation to generate ketene and hydrogen chloride, which formed the ketene...HCl complex.The fundamental vibrational frequency of HCl in the complex was observed at 2679 cm^-1, i.e. 191 cm^-1 below the frequency of the corresponding HCl monomer in solid argon.The fundamental frequency of DCl in the ketene-d2...DCl complex formed by photolysis of acetyl chloride-d3 was observed at 1939 cm^-1, i.e. 140 cm^-1 below the frequency of the corresponding DCl monomer in solid argon.
