Webdissociation energy. Thus, according to Table 1, the averaged ratio of the energy cost ot fluorine atoms Thzmation wider the effect of an electron beam to the energy o fluorine molecule dissociation amounts to 3.8±1.3. A photodissociation of molecules is capable ot providing the least values o:t atom energy cost. This is concerned with the ... The bond-dissociation energy (BDE, D0, or DH°) is one measure of the strength of a chemical bond A−B. It can be defined as the standard enthalpy change when A−B is cleaved by homolysis to give fragments A and B, which are usually radical species. The enthalpy change is temperature-dependent, and the bond … See more The term bond-dissociation energy is similar to the related notion of bond-dissociation enthalpy (or bond enthalpy), which is sometimes used interchangeably. However, some authors make the distinction that the … See more Bonds can be broken symmetrically or asymmetrically. The former is called homolysis and is the basis of the usual BDEs.
