Methyl-substituted 2-pentanones in the vapour phase

Values for 0i and 0,i were determined in the photolysis of two substituted 2-pentanones (Table 24). The quantum yields of acetone and olefin formation were found to be equal and independent of temperature. No wavelength dependence of the primary quantum yield 0n was observed between 3130 and 2654 A in the photolysis of methyl neopentyl ketone.
