Abstract
The spectrum first observed by Thrush during the flash photolysis of cyclopentadiene has been reinvestigated using deuterated compounds. Eight different spectra have been observed and have been assigned to the isotopic species: cyclopentadienyl-d0, -d1, -1,2-d2, -1,3-d2, -1,2,3-d3, -1,2,4-d3, -d4 and –d5. The isotope shifts and the absence of further deuterated species establish unequivocally the assignment of the carrier, and show furthermore that the five hydrogen atoms and five carbon atoms are effectively equivalent.
