Chemical CD oscillation and chemical resonance phenomena appear in a competitive chemical reaction system involving amplification. A pseudoenantiomeric mixture of an aminomethylenehelicene (<i>P</i>)-tetramer and an (<i>M</i>)-hexamer in toluene forms three states, namely hetero-double-helix <b>B</b>, hetero-double-helix <b>C</b>, and dissociated random-coil 2<b>A</b>. When the temperature of the solution is oscillated between -5 and 38 °C at a rate of 2 K min<sup>-1</sup>, Δ<i>ε</i> reaches max ...[more]
