The Raman spectrum of gaseous trichloroacetaldehyde (chloral) has been recorded from 20 to 3200 cm −1 . A series of three transitions (83, 76, 69 cm −1 ) has been observed for the low frequency torsional mode. The barrier to internal rotation has been calculated to have a value of 1.17 kcal mol −1 (409 cm −1 ) in the gaseous phase. This value is compared to the corresponding quantity in similar molecules.
