The laser-induced S 2 -S 0 fluorescence excitation and dispersed emission spectra of azulene and three azulene derivatives of C 2£ skeletal symmetry, 2-chloro-, 2-methyl-, and 1,3-dimethylazulene, have been measured under ultracold, isolated conditions in a supersonic expansion. The FT-IR spectra of
2-Aryl-N,N-dimethyl-1,3-imidazolidines and 2-aryl-1,3-dioxolanes were subjected to 70 eV spectral analysis. Fragmentation pathways for both series of compounds are suggested. Aryl us. benzylic hydrogen fragmentations were subjected to Hammett cr+p plots. Incipient charge on the benzyl carbonium ion
