| Abstract: | The conformational behaviors of monosodium glutamate(MSG) in a dehydration process were studied by Micro-Raman spectroscopy in combination with Hartree-Fock calculations using 6-31+G~* method.The dehydration process of the MSG droplet was performed by decreasing the ambient relative humidity(RH).The intensity ratio of the 935 cm~(-1) band to 884 cm~(-1) band(I_(935)/ I_(884)) kept decreasing when RH decreased.By optimizing the geometries with different fixed dihedral angles,the downtrend of(I_(935)/ I_(884)... |
