Silicon preparation/characterization

Preparation, characterization, and properties of silicon-containing triorganotin fluorides, both symmetrical and unsymmetrical, were investigated. It was observed that introduction of a trimethylsilyl group in the alkyl chain results in a considerable enhancement of solubility in various nonpolar solvents including dense carbon dioxide.

It is accepted that the features in the Raman spectra of amorphous solids resemble the vibrational densities of states (VDOS) of their crystalline counterparts [111]. The Raman spectrum of amorphous silicon is characterized by four broad bands around 160,300,390, and 470 cm [112,113]. They correspond to the features in the vibrational density of states of a-Si and are referred to as TA-, LA-, LO-, and TO-like bands, respectively [114]. In general, the TA/TO intensity ratio, their linewidths, and frequency positions depend on the method of preparation, deposition conditions, and the degree of structural disorder [115] (Fig. 16).

The increasing tendency of silanols to condense as the number of OH groups on a particular silicon increases means that relatively few silanetriols have been isolated and even fewer structurally characterized. A wide range of substituted arylsilanetriols have been prepared (102), but none have been studied by x-ray crystallography. The first silanetriol to be structurally characterized was c-C6HuSi(OH)3, which has a sheet structure comprising double layers of molecules joined in a... 

The goal of our investigations was to characterise the morphology of the sample, and to determine the size and location of the PTFE and silicone oil phases by different methods [46,47], For phase characterization using Raman microscopy, no special sample preparation was necessary. For FTIR imaging, microtomed sections (5 pm in thickness) had to be prepared by cutting the sample with a diamond knife at — 80°C ("cryo-microtomy") to prevent smearing and to obtain flat surfaces. 

We have recently prepared some new and very thermolabile CO- and N2 comPlexes derived from titanocene [1] or decamethyltitanocene [2], and have characterized them by their vibrational spectra. As well as "classical" matrix spectroscopy, we have used spectroscopy in liquid xenon (LXe). The application of chemistry and methodology indicates the decamethylsilicocene structure, which represents the first example of a stable jt-complex of divalent silicon [3]. Reaction with CO or N2 leads to the two title complexes [4] ...
