A nv.~.dif~Β’d mttltiplc reflt.'dion sysl.cm in ',.vhich the image of the source is focused into lhe flame in,/.tcad or on I.o the mirrm surlaΒ’cs has been devulolxd. It reduces troubles due to defocusing of the lighl beam by refraelive index gr:tdit, ms in IhΒ’ ll,,me and gives belter sp~ltial resolution. The Sw~m band~ of C: and the 4050A C., band have been observed in the 'l~:;tlhcr' of;, rich ~xy-llcdyPenc I~ame, and all Ihree syslem~ of Cli. as well as C z in the reaction zone.

The absorption spectrum of the cyclohexyl radical exhibits a pronounced shoulder in the region of 250 nm in contrast to the absorption of the cyclopentyl radical which decreases monotonically with increasing wavelength above 220 nm. In this region the cyclohexyl radical absorbs considerably more str
Splitting of UV absorption bands of the substituted pyridinyl radicals by formation of CT type dimers is discussed using an esciton model. From observed results and theoretfcal considerations a kind of twisted model is proposed in the dimer, where the two radicals lie one above the other in paraIfeL
