Vibrational Overtone Activation of Methylcyclopropene
Abstract
The photoisomerization of 1 -methylcyclopropene (MCPene) was studied at specific internal energies accessed by laser vibrational overtone activation. The vibrational overtone spectrum of the 6-0 and 5-0 CH stretches were observed for our synthesized mixture of 75% MCPene and 25% methylenecyclopropane (MCPane) . The overtone spectrum of neat MCPane was determined in the spectral regions. The transition wavenumbers were compared to the previously known members of the vinyl, methylenic and methyl vibrational progressions. Product yields from activation through the 5-0 vinyl and methyl CH stretches were determined using gas chromotography. Product ratios of 1,3-butadiene to 2-butyne were measured as a function of pressure and compared to the RRKM predicted yields. After careful measurements we conclude that at these photolysis energies methylcyclopropene does not produce methylene cyclopropane.... Overtones, Methylcyclopropene, Kinetic.
