摘要: Publisher Summary The aim of this chapter is to present in some detail a simple, qualitative framework for understanding the factors which go into creation reaction profile. Because question raised so fundamental —“What determines barrier any chemical reaction?”—the model encompasses within its single structure reactions as different electron-transfer reactions. It brings under one roof both thermal and photochemical processes. theory termed “configuration mixing (CM) model,” or when valence-bond configurations are solely utilized, “valence-bond configuration (VBCM) model” has been applied over recent years many these mentioned types. In view role played by quantum modern chemistry, it not surprising that theoretical basis CM goes back earliest days chemistry. fact, basic concept may be considered precursor resonance theory. concludes notion molecule “hesitates” between structures, borrows characteristics, finally adopts somewhat intermediate them, central “electronic behavior.” from yet powerful principle utility generality.
