Raman scattering and vibrational dynamics of MnCl₂·2H₂O

Abstract

The laser excited Raman spectrum of MnC12.2H20 has been reported in the 4000-150cm-' region and discussed in conjunction with the known IR spectra. The bands have been assigned to intend and librational modes of water and other lattice modes. It has been found that the correlation splitting parameter Av/v-.,, is distinctly larger for the librational modes than for the internal modes of water. The increase in intensity of the v 1 over the v, band of water in passing from the free to crystal water state and the low intensity of the librational bands have been explained.

“…The coordinated water can also be clearly seen in the IR spectra (see also Supporting Information). [24] The amount of water is critical, and a larger excess of it reduces the yield. Hence when we increased the MnCl 2 12 ] solution.…”

“…[21,22] We reported on the first monomeric Zn complex featuring κ 1 4 and four or more equivalents of tetramethylguanidine (tmg). [24] We also showed that reaction of [ZnEt(O 2 CN(iPr) 2 …”

Polarised IR and Raman spectra of non‐centrosymmetric Na3Li(MoO4)2· 6H2O crystal—a new Raman laser material

“…[21 -24] Static and dynamic models of the interactions between the water molecules in the unit cell have been considered. [25,26] The librational modes of the water units have been found in the regions 660-780 and 340-430 cm −1 , both in the IR and Raman spectra. [27 -29] The assignment of other external vibrations of the water units in the hydrates is not consistent.…”
