Zusammenfassung

Die Infrarot-und Raman-Spektren folgender Hydroxylamin-Derivate wurden registriert und zugeordnet: (CH3)3SiONH2 (1), (CH3)3SiONHSi(CH3)3, (CH3)3SiON[Si(CH3)3]2 (3), CH3ONH2 (4), CH3ON[Si(CH3)3]2 (5), CH3NHOCH3, CH3N[Si(CH3)3]OCH3, (C2H5)2NOH und (C2H5)2NOSi(CH3)3. Eine Normalkoordinatenanalyse für NH2OH,1, 3, 4 und5 zeigt, daß sich die Spektren durch Übertragung gleichbleibender Kraftkonstanten der Molekülfragmente wiedergeben lassen. O-und N-Substituenten beeinflussen die NO-Kraftkonstante nicht; die SiO-und SiN-Valenzkraftkonstanten sind mit 3,3 mdyn/Å bemerkenswert niedrig.

Abstract

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 and5 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).
