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.

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
