Analysis of the infrared spectra of some polydeuterated toluenes obtained by proton exchange with BF3-D3PO4 demonstrated the unreliability of this analytical tool in the 4000–900 cm−1 region. Useful correlations can be obtained in the 900–500 cm−1 region if suitable instrumentation is available. The previously unreported spectra of toluene-2,5-D, toluene-3,5-D and toluene-2,4, 6-D are described.
