Infrared absorption  spectra of complexes with phosphinic acids.
Zakirov Ildar Ilusovich

The IR spectra of mixtures of phosphinic acid (H2POOH) with deuterated acetone-D6, diethyl ether in the gas phase were recorded with a Bruker IFS125 HR spectrometer with resolution 0.5 см-1 at different pressures at the room temperature. The IR spectra of mixtures F2POOH with acetone, diethyl ether in solutions were recorder with a Nicolet 6700 spectrometer with resolution 1 см-1. The bands of the complexes were obtained by successive subtraction of the phosphinic acid monomers in the gas phase or dimers in solutions and acceptors spectra from recorded ones. The shift of ν(P=O) bands in the all spectra were observed. The ν(OH) band the complexes were obtained from the spectra of solutions. The shifts of the band relative to the corresponding phosphinic acid monomer one are compared with shifts of the ν(C=O) band in the IR spectra of complexes trifluoracetic acid and the same hydrogen acceptors.
