Polarized Raman spectra of single crystals of barium copper formate [Ba 2 Cu(HCOO) 6 ] at room temperature were recorded and analysed. The spectra were obtained for geometries allowing the observation of A(TO) and B (TO Y LO) species. The assignment of the fundamental modes was performed on the basi

β¦ Synopsis
Raman spectra of cesium triborate were recorded at room temperature and liquid nitrogen temperature and the infrared reflectance spectra at room temperature. The assignments of characteristic vibrational modes are presented. A comparison of cesium borate and lithium borate was made. A correlation exists between the LO-TO splittings of vibrational modes of borate crystals and their non-linear optical efficiencies.
