chiral molecule

chiral molecule,

another term for optical isomer. See Stereoisomers under isomerisomer
, in chemistry, one of two or more compounds having the same molecular formula but different structures (arrangements of atoms in the molecule). Isomerism is the occurrence of such compounds. Isomerism was first recognized by J. J. Berzelius in 1827.

Pseudoephedrine is a chiral molecule, meaning it occurs as in both "left-handed" and "right-handed" configurations which are not super imposable.
Whereas CD involves the ground state of a chiral molecule, CPL is emitted by a fluorophore if the excited state of the emitting species is chiral.
Both Hund's perturbation and parity violation terms are quite small for almost all the "stable" chiral molecules, in other words, the Hamiltonian of a chiral molecule is almost completely symmetric with respect to inversion, and the measurement of optical rotation has so far been nearly the only way to differentiate enantiomers.

In less than a decade, the X-ray pulse duration has been shortened from over 100 femtoseconds to 5 fs (and likely 0.5 fs later this year); full polarization control has been introduced, so we can see chiral molecules that are important for many pharmaceutical drugs; and a wide array of dual-pulse options have been developed that provide the ability to drive a system and monitor its response on timescales that range from femtoseconds to microseconds.
