✦ Synopsis

The f-value of the Z16Oi band of the free methyl radical W~ZI determined Pxperimentally as (1.2 t 0.2) x 10'2. The rate coefficient for combination was found to be (2.43 h 0.24) x 1013cm3 mal-lsec-1.

Rydberg series of the free methyl radical in the far ultraviolet were discovered by _Herzberg and Shoosmith [1,2]. The band at 2160A (PI -X)
