The spectra of tetraphenyl-cumulenes are investigated and discussed. The nonaene and the tetraene are new members of this group. A minor product in the reaction to the aliphatic pentaene cumulene with a new chromophor is studied. The addition of water lead to an allene ketone which has also a new chromophoric system. The reactivity of cumulenes lies between that of polyenes and polyynes
