摘要: The combination of ion-imaging and vacuum-ultraviolet (vuv) single-photon ionization is used to study the internal energy dependence relative photoionization yields C2H5,n-C3H7, i-C3H7 radicals following 266 nm photodissociation corresponding alkyl iodides. comparison ion images obtained by vuv radical with those two-photon-resonant, three-photon complementary IP3∕22 I*P1∕22 atoms allows extraction cross sections. Factors influencing appearance in different detection channels are discussed, including secondary fragmentation neutral radicals, Franck-Condon factors for process, unimolecular parent photoions.
