Section: A Hamiltoniana De Espalhamentounclassified
“…It is well established that the S-matrix version of the Kohn variational principle is to be preferred over the K-matrix version, which gives rise to the so called ''Kohn anomalies.'' 13 Here, we will use the T-matrix version, which is more stable than the S-matrix version when ͑locally͒ strongly closed DWs are used, as we will explain at the end of this section.…”

“…The first practical step is to reformulate the entire procedure in terms of mutually orthogonal bound and continuum functions. This can be done quite rigorously and follows from a property of the Kohn principle called transfer invariance which has been described elsewhere 7 , 8 . The matrix elements involving only bound functions can be evaluated using the standard techniques of bound-state molecular electronic structure theory.…”
