In the last years, Infrared Reflection-Absorption Spectroscopy (IRRAS) became a standard technique to study vibrational excitations of molecules. These investigations are strongly…
Separating the Material and Geometry Contribution to the Circular Dichroism of Chiral Objects Made from Chiral Media
Lukas Rebholz, Marjan Krstić, Benedikt Zerulla +4
The chirality of an object can be studied by measuring the circular dichroism, that is, the difference in absorption of light with different helicity. The chiral optical response o…
