High pressure exploration in the Li–Ln–V–O system

Abstract

Using in situ high pressure Raman spectroscopy, two structural changes were observed in a sample of composition LiLa5O5(VO4)2. Taking this account and by combining different conditions, three new compounds have...

Gladstone–Dale compatibility, electronic polarizability and vibrational spectroscopy of minerals and inorganic compounds with V4+O and V4+O2 vanadyl groups

“…Note: sherwoodite (Thompson et al, 1958;Evans & Konnert, 1978) is excluded from the table because there are no reliable data on the V 4+ :V 5+ ratio in this mineral and because the 14-vanadoaluminate cluster occurring in its crystal structure might need another treatment in the calculation of optical data.
