The infrared spectra of phenyl acetate, phenyl-d5 acetate, and phenyl acetate-d3 as solutions in carbon tetrachloride or carbon disulphide have been recorded in the 4000-100 cm-1 region together with the Raman spectra of the pure liquids. Infrared spectroscopy (IR) techniques determine the structures of organic molecules. IR spectra are quick and easy to run, and since the teaching labs are fortunate enough to have four of these instruments, students are encouraged to acquire spectra of compounds made in the laboratory throughout the first and second semesters of the lab course.
