The infrared (ir) multiple-photon photolysis of CH/sub 3/NC has been performed over the range 10 mtorr to 1.0 torr by using the 10.696-..mu..m line of a TEA CO/sub 2/ laser. The rotational and vibrational temperatures of CN(X/sup 2/..sigma../sup +/), resulting from the photolysis of CH/sub 3/NC, are hotter than those obtained in the ir photolysis of CH/sub 3/CN. Experiments which involved the time evolution of CH, CN, and C/sub 2/ along with stable product analysis have provided the basis for the possible mechanisms by which these species are formed. The major process of CH/sub 3/NC conversion with the 10.696-..mu..m line appears to be isomerization to CH/sub 3/CN and subsequent secondary photolysis of vibrationally excited CH/sub 3/CN, which also absorbs the 10.696-..mu..m line. Stable product analyses at pressures between 10 and 40 torr revealed the presence of C/sub 2/H/sub 2/, HCN, and CH/sub 3/CN. 2 figures, 1 table.
