Differential Optical Absorption Spectroscopy (DOAS) is a powerful remote-sensing method that exploits the distinctive, narrow-band absorption structures of atmospheric trace gases in the ultraviolet ...

Chiroptical properties arise from the interaction of chiral molecules with circularly polarised light, leading to phenomena such as optical rotation, electronic circular dichroism (ECD) and ...

Optical microscope image of a representative crystal that possesses centrosymmetry, yet shows differential absorption of circularly polarized light. The crystal is made of lithium, cobalt, selenium ...
