Dichlorostannylene complexes of group 10 metals, a unique bonding mode stabilized by bridging 2-pyridyldiphenylphosphine ligandsElectronic supplementary information (ESI) available: NMR spectra for [1][BF4] (1H,13C,19F,31P and195Pt), [2][BF4] (1H and31P), [3][BF4] (31P), [4][BF4]...
We recorded infrared, Raman, and surface-enhanced Raman scattering (SERS) spectra of metal−string complexes Cr3(dpa)4X2 (dpa = di(2-pyridyl)amido, X = Cl, NCS) and [Cr3(dpa)4Cl2](PF6) and dipyridylamine (Hdpa) to determine their vibrational frequencies and to study their structures....
IR and Raman spectra (organic substancesRaman and infrared spectra of intact and metal-substituted chlorophyll a were observed in the solid state and in solution. Ni, Cu, Zn, and Ag were used to substitute Mg. Nine series of metal-sensitive bands were found in both the Raman and infrared ...
The preparation of the mixed complexes [Ni(dmit)2(piperidine)2][NBu4] and [Ni(dmit)(pip)2] are reported for the first time and their electronic, IR and resonance Raman spectra are presented. The results suggest that previous assignments for bis-dmit metal complexes are not correct. In ...
We report UV photodissociation (UVPD) and IR-UV double-resonance spectra of dibenzo-18-crown-6 (DB18C6) complexes with alkali metal ions (Li+, Na+, K+, Rb+, and Cs+) in a cold, 22-pole ion trap. All the complexes show a number of vibronically resolved UV bands in the 36 00...

The species associated IR difference spectra of this state are in good agreement with the calculated difference spectra of the lowest energy 3 dd state using DFT. The calculated potential energy curves for all the complexes in the triplet manifold along the metal-ligand distance show that for [...
As expected, the 1H NMR spectra of all polymers obtained were similar to that shown in Figure 3b. The integrated ratio of Ha–d/Ht protons for all fac-Ir(ppy)3 end-functio- nalized PDAS was close to the theoretical value (12/9), as shown in Figure 3b. Therefore, all obtained ...
