This book is based on the reactions of thermal electrons with molecules. The ECD, negative-ion chemical ionization (NICI) mass spectrometry, and polaro-graphic reduction in aprotic solvents methods are used to determine the kinetic and thermodynamic parameters of these reactions. The chromatograph gives a small pure sample of the molecule. The temperature dependence of the response of the ECD and NIMS is measured to determine fundamental properties. The ECD measurements are verified and extended by correlations with half-wave reduction potentials in aprotic solvents, absorption spectra of aromatic hydrocarbons and donor acceptor complexes, electronegativities, and simple molecular orbital theory.

Figure 1. Absorption spectra of aromatic anions in ethyl alcohol, formed by electron attachment in pulse radiolysis, (a) Diphenyl in ethyl alcohol. The solid curve was obtained during the pulse. The dashed curve was obtained after a delay of 12 sec. and is thought to be the adduct radical Ci2Hu. (b) Anthracene in ethyl alcohol. This band of the anthracenide ion was observed spectrophotometrically at about 0.2 yjsec. after the pulse, (c) p-Terphenylide ion in solutions of p-terphenyl in ethyl alcohol. Spectra are...

Figure 2. Absorption spectra of aromatic cations in chlorinated alkane solvents, formed in pulse radiolysis. (a) Diphenyl in 1,2-di-chloroethane. The spectrum was obtained 2 yjsec. after the electron pulse. (b) p-Terphenyl in 1,2-dichloroethane. The spectrum was obtained 4 nsec, after the electron pulse. The band at 420 m may contain a small contribution from a long-lived species produced by the radiolysis, (c) trans-Stilbene in 1,2-dichloroethane, in 1,1,2-tri-chloroethane, and in 1,1,2,2-tetrachloroethane. Spectrum was obtained 1 fisec. after the electron pulse...

Recently certain anomalies in the ultraviolet absorption spectra of aromatic amino acids brought about by their combination in proteins have given evidence which, in conjunction with evidence from other sources, may throw some light on the structure of proteins (see Section VI).
