The substance used in the study, an organic compound called propylene oxide, made headlines back in 2016 when it became the first - and thus far, the only - chiral molecule
to be found in interstellar space.
For the first time, researchers have detected a chiral molecule
, propylene oxide, in interstellar space.
and continues to prove, that the use of the correct chiral molecule
can make all the difference in how effective an ingredient will be and, just as important, what reactions it will create.
Triple resonance for a three-level system of a chiral molecule

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.
A mixture that is racemic contains a chiral molecule
as well as its mirror image.
This year's Nobel Laureates in Chemistry have developed molecules that can catalyse important reactions so that only one of the two mirror image forms of a chiral molecule
exhibit different chemical and physical properties in the chiral environment.
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.
