Abstract

<jats:title>Abstract</jats:title> <jats:p>The charge–transfer spectrum of tetracyanoethylene with α-methylstyrene in 1,2-dichloroethane at 25°C has been measured at high pressures up to 1500 bar. Volume changes associated with the charge–transfer complex formation and the 1,4-cycloaddition at 1 bar are −6.9±0.6 and −29.2±0.7 cm3 mol−1, respectively.</jats:p>
