Abstract

Abstract: A reanalysis of the vibrational ground-state microwave spectra of various isotopic versions of propadienone including lines assigned to the new l-I3C isotope, and taking into account the molecular nonrigidity, has been undertaken in order to determine more precisely the molecular structure. The nonlinear heavy-atom chain is found to have a zigzag conformation with angles LC1C2C3= 144.5'and LOClC2= 169.4'. The vibrational potential ...
