| Abstract: | The space group theoretical analyses and assignment of the lattice modes of KDP crystal have been made, and the Raman spectra of their growth solution have been observed in different growth regions The attention is focused on the analysis of the 916cm -1 band arising from the H 2PO 4- anions in the interface between the KDP crystals and their growth solution This has been assigned to the asymmetrical stretching mode of the deformation P(OH) 2 From these results, the growth unit of KDP crystal has been concluded to be the dimers of H 2PO 4- anions |
| Keywords: | Raman KDP lattice vibrational modes space group growth mechanism |
