DOI: 10.1016/j.ccr.2017.03.002
Abstract: Abstract The current usage of bond-length/bond-strength (BLBS) correlations, namely, that a shorter bond must be associated with larger dissociation energy and/or force constant, is appraised. The numerous exceptions to these rules are noted. The originators… read more here.
