title: [FTIR and FT-Raman spectroscopic investigation on two complexes of La3+ with galactitol].
abstract: FTIR and Raman spectroscopy were used to investigate the two complexes of LaCl3 with galactitol in this paper. The results shows that La ion can complex with galactitol in 1:1 and 2:1 proportion. The FTIR and Raman spectra of the two complexes both exist some differences that prove LaCl3 and galactitol really form two different complexes. In the FTIR spectra nu OH is strong peaks and nu CH peaks are very weak whereas nu CH pband become stronger than nu OH peaks. So FTIR and Raman spectra can provide complementary information.
