2,4-Trimethylpentane has been photolysed at 123.6 and 147 nm at substrate pressures of 1-55 Torr, and conversions of 0.02-0.4%. Use of radical scavenging techniques show the existence of three molecular primary C8H 18 ? i-C4H8 + i-C4H 10 (i) ? CH4 + C7H14 (ii) ? C3H6 + neo-C5H12 (iii) C 8H18 ? Me + C7H15 (iv) ? But + Bl (v) ? Pri + neo-C 5H11 (vi) processes (i)-(iii). In addition to processes (i)-(iii), radical processes (iv)-(vi) also occur. Deactivation of the excited molecular and radical primary products is incomplete, and secondary fragmentation reactions occur.
