摘要：

The photolysis of cyclobutanone has been investigated between 40 and 250° and in the pressure range 5.0-40.0 torr of cyclobutanone. Quantum yields for CO, C2H4, C3H6, and c-C3H6 have been determined as a function of temperature, pressure, and inert gas. The yield of C3H6 was found to increase with decreasing cyclobutanone pressure and with shorter wavelengths, while the yield of c-C3H6 was unaffected. Added gas lowered the C3H6 yield. No effect was noted on the c-C3H6 yield. Isomerization of cis- to trans-butene-2 was observed. A mechanism involving formation of C3H6 from an excited triplet cyclobutanone, possibly involving a diradical intermediate, has been proposed.
