Abstract:
Guatemala is another jade commercial origin in addition to the Myanmar. The Guatemalan jade is usually an assemblage of a variety of mineral compositions, and the mineral composition is unique and different from the Myanmar jade. The characteristics of the structures and paragenetic minerals of the purple and gray-green jade from Guatemala were studied by laser Raman spectroscopy analysis. The results show that the jadeite is a major constituent mineral in Guatemala jade, associated by a variety of coexisting minerals. The paragenetic minerals in Guatemalan jade can be divided into five categories, including the dark minerals hornblende, dolomite, omphacite, chlorite, and light-colored mineral apatite. The hornblende, dolomite, omphacite and chlorite are also the paragenetic minerals in the Myanmar jade, but the apatite is almost invisible in the Myanmar jadeite.

Raman Spectroscopy: Overview
However, a small fraction of the scattered light exhibits a frequency shift due to the exchange of energy between the incident photons and the...
X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...
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...
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...
