TL;DR: In this article, the ingrared spectra of trimethyl- and triphenylphosphine oxide and a number of their complexes with various transition-metal cations were examined, and an explanation in terms of a lowering of the P-O bond order was proposed.
Abstract: S>The ingrared spectra of trimethyl- and triphenylphosphine oxide and a number of their complexes with various transition-metal cations were examined. Complexformation causes the P-O stretching frequencies to shift approximately 50 cm/sup -1/ to lower values. Since a simple linematic effect would raise the frequency, an explanation in terms of a lowering of the P-O bond order is proposed. (auth)

Journal ArticleDOI
TL;DR: In this article, the anhydrous nitrates of manganese, copper, zinc, and mercury indicate the presence of covalent metal-nitrate bonds, while the hydrated thorium nitrate exhibits bands characteristic of a co-ordinated nitrato- group.
Abstract: Infrared spectra for the anhydrous nitrates of manganese, copper, zinc, and mercury indicate the presence of covalent metal-nitrate bonds. The anhydrous nitrates of cobalt, silver, cadmium, and lead have spectra characteristic of the nitrate ion. Frequencies for the hydrated nitrates of iron, cobalt, nickel, copper, zinc, and cadmium are given for comparison. Hydrated thorium nitrate exhibits bands characteristic of a co-ordinated nitrato- group. (auth)
