Packet B: Tossup 19

The response of a device named for this process to hydrocarbons is directly proportional to the number of carbon atoms by an “equal per carbon” rule. Direct analysis in real time induces this process through the production of metastable species in an ambient form of it. (10[1])Excess methane gas is used to induce this process in its “chemical” type. This process (10[2])partially names a detector in gas chromatography (10[1])that uses (10[1])hydrogen flames. (10[3]-5[1])An energy (10[3])for this (10[1])process (10[3])can be calculated from (10[4])HOMO (10[2])(“ho-mo”) energies (10[1])according to (-5[1])Koopman’s (-5[1])theorem. (10[4]-5[1])A “soft” form (10[2])of this process (10[4])occurs after (10[1])matrix-assisted (10[3])laser (10[1])desorption. (10[3]-5[3])Products generated by this process are often analyzed (10[1])by (10[1])distinct mass-to-charge ratios. (10[1]-5[1])For 10 points, (-5[3])name this process of removing electrons (10[2])to generate (10[2])charged species. ■END■ (10[24]0[7])
