| Abstract: | The infrared and Raman spectra of various flourinated ethylamines have been obtained for different phases. Emphasis has been put on the conformational behaviour in inert gas matrices. Some preliminary results for 2-fluoroethylamine and 2,2,2-trifluoroethylamine are given in the present communication. The two gauche conformers of 2-fluoroethylamine which are observed in the vapour phase are also present in the argon and nitrogen matrices. A conformational change, possibly to an anti conformer, is observed after a few hours in the argon matrix. For 2,2,2-trifluoroethylamine no conformational change is observed in the matrices. |
