Electronic Structure, Spectroscopy, and Photochemistry of Organic Radical Cationsructure of organic radical ions, as manifested by their sometimes very vivid colors, which often stood at the origin of the fascination with these species, as can be seen from the choice of words used in the following quotes:

ESR Studies of Radical Cations of Cycloalkanes and Saturated Heterocycles. As a result, such bonds are weakened and elongated. The presence of a heteroatom in a saturated system gives a SOMO which involves the lone-pair orbital(s). In such cases, the radical cations usually have a π-type character, and the unpaired electron delocalises to hydrogens on the adjacent carbons . hyperconjugation.

Radical Cations of Aliphatic Ethersor studying the internal rotation of the methyl group while the cations of acetals and dioxanes are a suitable system for analyzing the orbital interaction, for example. In the succeeding sections we will deal with several ethers dividing them into sections according to the topic to be emphasized.
