sphene's Usage Examples:

ore minerals, borate minerals (tourmaline) and accessory phases such as sphene, beryl or topaz.

peridot, tourmaline, topaz, garnet, red spinal, pargasite, diopside, sphene, apatite, azurite, rose quartz, and agate.

However, the molecular weight determination and X-ray crystallographic analysis later proved that this diphosphene only had a P-P single bond.

sphene, morganite, and quartz Image shows deep purple apatite from Shengus.

Then the research to diphosphenes kept silent over almost 20 years until Masaaki Yoshifuji and his coworkers isolated the unprecedented diphosphene--bis(2,4,6-tri-tert-butylphenyl)diphosphene in 1981.

Spectroscopic Properties Diphosphene compounds usually exhibit a symmetry-allowed (\pi \rightarrow \pi^*) (intense) and symmetry-forbidden electronic transitions (n\rightarrow \pi^*) (weak).

The phosphorus dichloride dimerized to a diphosphene after magnesium extracted two chlorine from (2,4,6-tri-tert-butylphenyl)phosphorus dichloride.

Apart from iron, other similar transition metal complexes by reacting diphosphenes with transition metal carbonyls of nickel, tungsten and chromium were discovered and they all exhibited Z configuration.

31P, 1H and 13C spectras all proved the formulation of this alkyl-group stabilized diphosphene.

In volcanic rocks perovskite and sphene are not found together, the only exception being an.

biotite, chlorite, tourmaline, epidote, apatite, garnet, hornblende, augite, sphene and pyrites.

specimens of glaucophane-epidote schist, containing garnet, sphene and diallage collected by Eccles from several feet below the summit of Monte Viso were.

Also the observed strong Raman shifts for and suggest stronger dipnictenes feature of diphosphene compared with P-P single bond.
