Laser Raman Spectra

The laser Raman spectra of the hydroxo-bridged platinum(II) complexes, di-μ-hydroxo-bis(diammine) platinum(II)-nitrate [(NH3)2Pt(OH)2Pt(NH3)2](NO3)2, and isotopic derivatives involving the atoms H/D and 16O/18O are recorded in the solid state in the range 0–4000 cm−1. The infrared spectra of the complexes are recorded in KBr pellets in the range 200–4000 cm−1. Assignments of the different lines for the nitrate ion, the ammonia molecules, the hydroxo groups, and the square planar skeleton vibrations of the complex and its isotopic analogs are given.

Laser Raman Spectra

Laser-Raman spectra of 12 acyclic terpenoids has been recorded. Assignments were made for stretching mode vibrations of carbon-carbon double bonds by comparison with infrared spectra. The results of intensity and depolarization studies are discussed.

The ir and laser Raman spectra of η5-C5H5Mn(CO)2(CS) and η5-C5H5Mn(CO)(CS)2 have been investigated. In the case of the monothiocarbonyl complex, vapor phase, solution, and solid-state measurements were made, while for the dithiocarbonyl, only solid-state data were obtained. The vibrational spectra of both complexes have been assigned satisfactorily in terms of the C5v and Cs local symmetries of the η5-C5H5—Mn and Mn(CO)2(CS) (or Mn(CO)(CS)2) moieties, respectively. The effect of change of state on the spectra of the monothiocarbonyl complex is discussed.

Laser Raman Spectra

The solid-state infrared (i.r.) and laser Raman spectra of the halopentacarbonylmanganese(I) derivatives, Mn(CO)5X (X = Cl, Br,and I), have been recorded in the C—O stretching and the low frequency (700–33 cm−1) regions. The i.r. overtone and combination spectra recorded in the regions 2800–2250 and 1350–700 cm−1 have been used to help in the assignment of some of the low frequency fundamentals. The solid-state i.r. and laser Raman spectra of the dimeric halotetracarbonylmanganese(I) derivatives, [Mn(CO)4X]2 (X = Br and I), have been recorded in the C—O stretching and the low frequency regions for comparative purposes and shown to be consistent with the expected D2h symmetry of the molecules.

Laser Raman Spectra

Zeise's salt, anhydrous and monohydrate, has been prepared by a new method similar to the original method used by Zeise. The infrared and laser Raman spectra of the anhydrous Zeise's salt together with the infrared spectra of the deutero and bromo analogs, are reported and discussed. The vibrational spectra are interpreted in terms of a cyclopropane-like ring structure, obtained by the insertion of the platinum atom into the double bond.

The infrared spectra from 4000–250 cm−1 and the laser Raman spectra of NOAsF6, NO2AsF6, N2F3AsF6, F2NOAsF6, NOSbF6, NO2SbF6, N2F3Sb2F11, and F2NOSb2F11 are recorded. Eight of the nine fundamentals expected for the N2F3+ cation can be observed and are tentatively assigned. The vibrational spectra of the MF5 adducts are in agreement with an ionic formulation; however, the mutual exclusion rule for infrared and Raman active vibrations appears to be relaxed and one of the fundamentals v5 [F2g] is split into a doublet in almost all cases.
