Abstract:

The photoisomerization of methyl isocyanide to form acetonitrile induced by excitation into the fourth about 1 kcalmole above the activation barrier and fifth about 8 kcalmole above the barrier C-H stretch vibrational overtone levels is reported. Four photolysis wavelengths within the 5-0 band contour and three within the 6-0 contour were selected. The specific rate constant, kE, derived from Stern-Volmer plots with increasing excitation energies selected from across the rotational band contours, increase monotonically. The experimental kE agree with RRKM calculated values.
