  The chiral induced spin selectivity effect is an excited states phenomenon,
which can be probed using photo-spectroscopy as well as transport measurements.
On the one hand such measurements represent averaged quantities, on the other
hand nearly all theoretical descriptions, with only a few exceptions, have been
concerned with energy dependent properties of the pertinent structures. While
those properties may or may not be relevant for the chiral induced spin
selectivity effect, many of those properties have been attributed as being the,
or part of the, origins of the effect. Here, it is demonstrated that, for
instance, the spin-resolved transmission provides little, if any, information
about the chiral induced spin selectivity effect. Moreover, although effective
single-electron theory can be used in this context, reasons are given for why
such descriptions are not viable.
