• The γ-radiolysis of benzene solutions containing carbonyl sulfide, nitrous oxide, and carbon dioxide has been investigated at room temperature and at 0°C. Carbonyl sulfide was shown to be an effective electron scavenger and to give carbon monoxide as the product. By comparing the solute concentration dependences of <I>G</I>(N<SUB>2</SUB>) and <I>G</I>(CO), it was concluded that the collision of secondary electrons with benzene does not efficiently produce the first excited singlet state, the <I>G</I>-value of which is less than 0.2 if it is produced at all. The concentration dependences of the <I>G</I>(CO) and <I>G</I>(phenol) from the benzene solution of carbon dioxide also suggested that the superexcited state or the highly-excited state of benzene is too short-lived to transfer its energy to the solute.
