Popis:	The enhancement factors of the 1H polarization induced in radical pairs generated by α-cleavage of 12CO- and CO-labelled ketones deviate from the ratios expected on the basis of the relative abundances of the respective carbon isotopomers. For dibenzyl ketone, the ratio of absolute CIDNP intensities of the 1H(13C) doublet (90% 13CO) to the 1H(12C) singlet (10% 12CO) was found to be >9:1 at 58·3 kG and
