✦ Synopsis

Eiectronicalfy excited carbon atoms in the lowest lying singtet state, C(Zf13.$ ~ have been monitored directly by photoelectric measurement of the attenuation of the resonance transition C(VYI~P* -2lD2) at 193.1 nm. The rate of decay of Lhe atom has been measured in the presence of hydrogen an fd nitrogen, yielding the following abso'tute rate constants at 300°K: W$f f N2 * CH + A, k = (2.6 f 0.3) x IO-l* cm3 molecule-l see-l, C(ZLDZ) + N2 -+ C(23PJ) f N2, fi = (4.2 A 1.2) x lo-12 cm3 molecule-l see-l.
