Teaching CSIR NET Mock Test Series Chemical Sciences Characterisation of Inorganic Compounds EPR Spectroscopy
The reaction of V2O5 with an ethanolic HCI produces a species X, which gives an EPR spectrum with an eight-line 51y hyperfine coupling (51V: I = 7/2) and a strong infra-red absorption in the region of 950 - 1035cm-1.x contains a
