Organic Esters

The infrared spectra of fourteen organic esters of phosphorus containing dimethylamino groups, and two esters containing diethylamino groups have been examined over the region 5000 to 670 cm.−1 (2 to 15 microns). Correlations have been obtained between absorption band frequencies and the presence of dialkylamino groups in the molecule as an aid to their identification in the spectra of phosphorus compounds. A number of compounds of the pyrophosphate type have been examined and absorption associated with the (P—O—P) linkage has been found in the 950 to 910 cm.−1 (10.5 to 11.0 micron) region. Some criteria are proposed to distinguish absorption by the (P—O—P) linkage in this region.
