Abstract A distinct phase effect was observed on the formation of13NH3, H13NOx and [13N]-amide in pile-irradiated butyric-d7 acid, although the magnitude of the effect was rather smaller than that in deuterated trifluoroacetic, acetic and propionic acids previously reported. In frozen butyric-d7 acid, most of13N was found in the forms such as13NH3 (54.8±0.7%), H13NOx (26.8±0.6%). and [13N]amide (15.9±1.8%). The yields of HC13N and [13N]aminobutyric acid were only 0.6±0.3 and 1.2±0.3% even in the liquid, respectively. The scavenger effect of acetic anhydride-d6 on the formation of13NH3, H13NOx and [13N]amide was examined. In liquid and frozen carboxylic acids, the yields of13NH3 and H13NOx were proportional and inversely proportional to the number of hydrogen atoms in a target molecule in the region of the number of hydrogen from unity to eight.
