| chiral-induced spin selectivity
(CISS) |
preference
for electron
spin orientation and propagation direction in charge transport or
transmission through left- vs right-handed nonsuperimposable
molecules |
(1) |
| spin selectivity (S) or spin polarization (P) |
S (or P) = (I+ – I–)/(I+ + I–), where I+ and I– are the intensity of the experimental
measurables, for example, current, rate constant, etc., for the spin oriented parallel and antiparallel to the electrons’
velocity |
(1) |
| spin–orbit (SO) interactions
(SOI) or spin–orbit coupling (SOC) |
interactions between the
electron spin and the orbital motion inside a potential; in CISS,
the structural chirality causes a significant coupling between the
electron spin and the angular momentum despite the light atoms |
(13) |
| magnetic exchange effect |
short-range interaction
between electrons imposed by symmetry requirements on spin state |
(14) |
| optical chirality density |
describes the local handedness
of an electromagnetic field that depends on uniquely defined and physically
observable field quantities |
(15, 16) |
| chirality
transfer or imprinting |
phenomenon by which achiral
matter acquires chiral–optical properties |
