Thermal energy reactions of C+(2P) and C(1D,1S) with CH3OH, C2H5OH, n-C3H7OH and i-C3H7OH to give CH(X2Π) radicals have been investigated by observing laser-induced fluorescence (LIF) spectra of CH(A—X) in a flowing afterglow. In the hydride ion abstraction by C+(2P), only CH3OH exhibited the CH(A—X) LIF spectrum with a vibrational distribution of 1.0 : 0.62 for v″ = 0 and 1, respectively. On the other hand, the CH(A—X) LIF spectra exclusively from v″ = 0 were observed in the reactions of C(1D,1S) with all alcohols studied. By isotopic substitution for CH3OH it was shown that the CH(X) radicals arise from the selective attack on the methyl site in the reactions of C+(2P) and C(1D,1S) with methanol.

Relative values of the total chemiluminescence cross.section for the crossed molecular beam Ca∗+SF6→CaF(A2Π)+SF6 reaction have been measured as a function of collision energy. Both metastable calcium atom states 3P1 were produced by low voltage de-discharge while translational excitation of the SF6 beam was achieved via the seeding technique. Whereas chemiluminescence yield from the CaF(A2Π) was observed from both of the metastable atom reactions, no chemiluminescence signal was detected from the ground atom reaction even though enough translational excitation was used to produc.e that excited product. By changing the discharge conditions different metastable concentrations were produced to measure the state-to-state cross-section for both 3P and 1D reactions, as a function of collision energy, up to 0.6 eV. Laser induced fluorescence of the atomic 4s5s 3S1←4s4p3PJ∘(J=0,1,2,3) lines have been measured to account for the metastable population in the J=1 level.
