The photochemistry of ketene has been studied at 3130, 3340 and 3660 Å. A chemical trapping technique was used to determine the relative singlet methylene quantum yields. At a pressure of ≈ 120 torr the 3130:3340:3660 Å CH2(1A1) quantum yield ratio is 1.0:0.16:<0.0006. One of the major implications of this result is that the fraction of methylenes which are singlets at 3660 Å is smaller than reported previously.
