The various elements in platinum cufflinks have different properties and their uses are not the same

Usually in the infrared region is divided into the baseband (also known as the District of functional groups ,4000-1500cm-’) and fingerprint region (1500-400cm-1), the two regions. Nature, mostly natural gemstone cufflinks containing hydroxyl and H2O, the corresponding stretching vibration caused by the mid-infrared absorption bands are mainly concentrated in the functional group area 3800 ~ 3000cm-1 wave number range. Infrared absorption bands caused by the bending vibration is changed greatly, most gemstone cufflinks infrared absorption bands bit 1400 ~ 17000cm-1 wave number range of Under normal circumstances, the specific wave number position of the hydroxyl or water molecules, also controlled by the size of the hydrogen bonding in the gemstone cufflinks. The symbol pf platinum cufflinks is Pt, which is silver gray and the proportion is 21.35, melting point 170 ℃, Mohs hardness of 4-4.5 degrees.
As for the specific wave number, depends on the size of the hydrogen bonding within the various types of gemstone cufflinks. Compared with the crystal water or structural water, symmetric and asymmetric stretching vibration of adsorbed water causes the infrared absorption of the wide band center bit 3400cm-1. It is chemically stable, free from the corrosion of acid-base on the cufflinks. For example, prevalent in the crystal structure of natural turquoise water of crystallization and adsorbed water, which caused by the hydroxyl stretching vibration infrared absorption Rui bands in 3466cm-1, 3510cm-1 Department and caused by the ν (the MFe Cu OH) stretching vibration infrared absorption bands at 3293cm-1, 3076cm-1, mostly soothing a wide spectrum of state distribution. Meanwhile, in the fingerprint region shows the infrared absorption bands caused by the stretching and bending vibrations of phosphate groups.
    The contrary in the area of functional groups, Gilson imitation turquoise in the apparent lack of natural turquoise unique to the stretching vibration of hydroxyl and water molecules caused by infrared absorption bands, at the same time show caused by the high polymer νas (CH2) asymmetric stretching vibration The infrared absorption sharp spectrum (2925cm-1), νs (CH2) symmetric stretching vibration caused by the infrared absorption of the sharp band (2853cm-1), the accompanied νas (CH2) asymmetric stretching vibration infrared absorption sharp band (2959cm-1 ). Fingerprint region, characteristic infrared absorption bands of carbonate foundation group vibration. The test results show that, commonly known as the Gilson law turquoise it is to suppress carbonate imitation turquoise. The various elements in platinum cufflinks have different properties and their uses are not the same.
Similarly, Flux synthetic emeralds by hydrothermal method synthetic emerald infrared absorption spectrum of the anhydrous molecule stretching vibration absorption bands given to distinguish. Flux synthetic emeralds under the conditions of high temperature molten crystal, there is generally no water molecules in its structure channels; Hydrothermal Synthesis of emerald crystal growth under hydrothermal conditions made in its structure channels there is often a different amount of water molecules and a small amount of perchlorate ion (mineralizer).  In the presence of impurity atoms in the diamond form and type of Diamond C atoms, when a small amount of N, B, and H impurity atoms in the lattice, allows the physical properties of diamond such as color, thermal conductivity, electrical conductivity changed significantly. Since the platinum was found later, its functions as cufflinks, jewelry, crafts, and currency can not do much than the gold and silver.
