Abstract
AbstractGrimme's Continuous Chirality Measure (
) was developed for comparisons of the chirality of the electronic wave functions of molecules, typically in their ground states. For example,
,
and
for alanine, hydrogen‐peroxide, and for achiral molecules, respectively. Well‐designed laser pulses can excite achiral molecules from the electronic ground state to time‐dependent chiral superposition states, with chirality flips in the femto‐ or even attosecond (fs or as) time domains. Here we provide a time‐dependent extension
of Grimme's
for trailing the electronic chirality flips. As examples, we consider two laser driven electronic wavefunctions which represent flips between opposite electronic enantiomers of oriented NaK within
and
. The corresponding
vary respectively from
or from
to
, and back.
