Abstract
The ion (C6CH2)(.-) is formed in the gas phase by the process -C=C-C=C -C=CH2OEt --> (C6CH2)(.-) + EtO., and charge stripping of the product radical anion yields the carbenoid neutral C6CH2; this can be either a singlet (the ground state), which is best represented as the carbene :C=C=C=C=C=C=CH2, or a triplet; the adiabatic electron affinity and th e dipole moment of the carbenoid neutral are calculated to be 2.82 eV and 7.33 D respectively.
