Rebbert, P. Ausloos Title: Photolysis of methane: Quantum yield of C(1D) and CH Journal/Source: J. Photochemistry, 1 (2), 171-176, (1972-1973); doi:10.1016/0047-2670(72)85005-6 Data: Energy/Wavelength range: 104.8 - 106.7 nm; 123.6 nm Resolution: Temperature: Temperature dependence: Pressure/Concentration: Phase: gas pH: Comments: It is demonstrated that C(1D) and CH(2Pi) species are formed in the photodissociation of CH4 at lambda = 123.6 nm [PHI(C) = 0.4 ± 0.1 × 10-3, PHI(CH) = 5.9 ± 0.5 × 10-2] and at lambda = 104.8-106.7 nm [PHI(C) = 6.5 ± 0.5 × 10-3, PHI(CH) = 0.23 ± 0.03].
