The following conclusions have been drawn: (i) The added SO2 acts mainly as a radical scavenger. (ii) The added NO shows not only the effect of radical scavenging, but also other effects. Therefore, it is inadequate to use NO as a simple radical scavenger, (iii) The C7-C12 products are formed from a combination reaction of alkyl radicals, but not from an ion-molecule reaction, (iv) The formation of C6H13+ ions by the direct action of radiation is suggested, (v) The G-value of ionization is evaluated to be 4.0. A brief discussion concerning the formation of N2 in the presence of N2O is also given.Read More
