The bond dissociation energy of Co has been measured by the onset of predissociation in a dense electronic spectrum by the detection of the fragment Co ion. The value obtained, D (Co ) = 2.765卤0.001 eV, compares well to the previously accepted value of 2.75卤0.10 eV, obtained using ...

Bond dissociation energy是指特定的一个化学键断开所需要的能量,而bond energy通常是指一类化学键的平均能量。比如氢氢键的bond dissociation energy是断开一个特定氢氢键所需的能量,而氢氢键的bond energy则是多个氢氢键断开或形成能量的平均值。 起源与发展: Bond energy的概念最早可以追溯到19世纪,随着化学研究的...
A number of values for the bond dissociation energy (BDE) of the carbon–fluorine bond in CH3F have been reported, with a typical value in the region of −110 kcal mol−1.4b,5 Thus, the C–F bond is the strongest carbon–atom single bond and this is reflected in the uniqu...
