Infrared and Raman spectroscopic studies on the hydrogen- and deuterium-bridge association of 2,2,2-trichloroethylamine

Within the framework of infrared spectroscopic investigations of differently substituted ethyl amine, the effect of chlorine substitution on the hydrogen and deuterium bridge association was investigated by the example of 2,2,2-trichloraethyl amine. The CCl3CH2NH2 was synthesized and prepared for the measurements; furthermore, important physical data for spectroscopic investigations were determined. First of all, the infrared gas spectrum (4,000 to 500 cm-1) and the Raman liquid spectrum (3,500 to 50 cm-1) of the pure compound and the N-dideutero compound were registered at room temperature. All bands appearing in the spectra were assigned; with the exception of the NH2- and ND2-torsional wave, all basic waves were dealt with. The infrared spectra of the liquid compound and of the binary and ternary solutions were recorded in the region of the NH2-stretching frequencies at temperatures between +20 and -1000C. (orig./LH)
