VIBRATIONAL SPECTRA AND NORMAL COORDINATE ANALYSIS OF SOME METHYL- AND TRIMETHYLSILYLHYDROXYLAMINES

The infrared and Raman spectra of the hydroxylamine derivatives quoted above were recorded and frequencies assigned. A normal coordinate treatment of NH2OH, 1, 3, 4 and 5 showed that the spectra can be explained by a single force field set up by transferring force constants from the different fragments of the molecules. The NO stretching force constant remains unaffected by different substituents. The SiO and SiN stretching force constants are remarkably small (c. 3.3 mdyn/Å). © 1969 Springer-Verlag.
