“…Incidentally, [PO^], [HP042-], and [H2P04-] can be expressed (Sato et al, 1991;Bellamy, 1980;Colthup et al, 1964) as point groups T<¿, C3u, and C2u, respectively. The IR spectra of H3P04, H2P04-, HP042-, and PO.13-are wellknown.…”

“…The fingerprint regions are 2800-and 2400-cnr1 peaks for HsP04, 540-and 450-cm-1 peaks for H2P04-, 1230-and 1076-cm-1 peaks for HP042-, and 1080-cm-1 peak for 04®-. P043-is a tetrahedron structure (Sato et al, 1991;Bellamy, 1980;Colthup et al, 1964) with phosphorus as the center atom. The regular tetrahedron structure has four basic vibration modes: vi is the symmetrical stretching vibration Ai, y2 is the double-degeneracy vibration E with deformation, v3 is the triple-degeneracy vibration F2 of stretching type, and y4 is the tripledegeneracy vibration F2 of deformation type.…”

A linear empirical correlation was established between Raman stretching wavenumbers of phosphorus-oxygen bonds and their bond lengths in inorganic crystalline phosphates. Although established on samples of inorganic crystalline phosphates, the correlation can be applied to glassy and amorphous phosphate materials (GAMs). Their unpolarized vibrational spectra are often similar because they are determined largely by short-range order. The correlation was used to predict P -O bond length in the a-form of Li 3 PO 4 , which is stable over only a small range of temperatures below the melting-point. It can also be used to estimate the length of P -O single bonds, terminal P -O and O -P -O chain bonds and terminal double bonds in many technologically important amorphous materials containing phosphate groups. This correlation is expected to offer invaluable insight into the structures of phosphate species for which diffraction or other spectroscopic techniques provide incomplete structural information. That would enhance the value of Raman spectroscopy as a complementary technique in structural studies of phosphates.
