Cyclopropenyl radical
WebCyclopropenyl radical is a 3 π-electron cyclic system where the carbon atoms are adjacent with each carbon 2p z orbital contributing 1 electron to the HMO π-electron system. The three atomic orbitals (AOs) combine to form molecular orbitals (MOs). Labeling the three carbons as 1, 2 and 3, ... WebDec 20, 2013 · The ionization energy (IE) of the 3-cyclopropenyl radical (6.00 ± 0.17 eV) was measured in the gas phase by reacting 3-cyclopropenium cation (c-C3H3(+)) with a series of reference reagents of known IEs. This result was combined in a thermodynamic cycle to obtain the heat of formation of c-C3H3(•) (1 …
