Owing to the low ( Ta ) , signals of its fluoride complexes were not observed . In the spectra of the extracts , signals only of HF and TaF 7 are observed . Under the studied conditions , titanium is extracted insignificantly .

Four Raman lines are observed : a line due to the totally symmetric vibration vi ( ai ) , a line due to the doubly degenerate vibration v2 ( e ) , and lines due to the triply degenerate vibrations v3 ( t2 ) and v4 ( t2 ) .
