For solutions with CAg < 10 mol / l and CAg > 10-3 mol / l , the positions of maxima markedly differ . In the first case , the maximum of the band retains its position ( ± 50 cm1 ) up to Cu / CAg = 1.2 and then shifts to the absorption ...

In the spectra of complexes I - III , the position of the bands v ( C - H ) and v ( C = C ) is the same as in the spectrum of VTE , whereas the heterocycle vibration band shifts to higher frequencies ( to 1483 cm - 1 ) .
