| Popis: | In the infrared multiphoton dissociation (IRMPD) of (CH 3 ) 2 NH (DMA) and (CH 3 ) 3 N (TMA) molecules, in the medium pressure domain (10 Torr), the CH 3 N and NH bonds can be easily broken to produce CH 3 and other free radicals. In TMA and DMA IRMPD it has been observed that generated CH 3 radicals react: (1) with hydrogen to produce CH 4 , (2) with one another to form C 2 H 2 , C 2 H 4 , C 2 H 6 and (3) with the neighboring molecules to produce heavy compounds. The radicals which result after the breaking of H 3 CN and NH bonds can isomerize to produce HCN or NH 3 . Contrary to the predicted polymer ((C 2 H 5 N) n ) reported to appear in the UV and thermal decomposition of DMA in the IRMPD process we measured appreciable quantities of heavy compounds like: TMA, (CH 3 ) 2 NCH 2 N(CH 3 ) 2 (I) and (CH 3 ) 2 NCH 2 CN (II). The data obtained allow us to identify the dynamic process of the IRMPD and to do a kinetical approach of the radicals yielded. |
