Abstract

In the flash photolysis of thiophene diluted with argon, a transient absorption spectrum in the region 3770Å and 4170Å has been observed. The new absorption spectrum which consists of about 30 narrow and sharp red degraded bands could be analysed into an electronic system with the origin band at 4113.8 Å. The bands could tentatively assigned to the CH radical.
