✦ Synopsis
Near resotlsnce vibronic interactions in the Born-Oppenheimer approximation -pertinent to radiationless transitions and inhomogeneous line broadening -are shown to be independent of the refevant eIectronic energy separation and to be practically equivalent to those deduced in the crude adiabatic scheme. The present theoretical results agree with those previously deduced by the authors in alternative procedures. The superiority of the B-O approximation for resonant interactions of thi8 type -which rests on the belief that the off-diagonal elements arising in this scheme are smaller than those resulting in alternative schemes and inversely proportional to the electronic energy separation -is therefore questionable.
