Chiroptical spectrophotometer and analytical method for optically anisotropic samples

Chiroptical spectrophotometer and analytical method for optically anisotropic samples

Posted on August 30, 2021July 23, 2021 by Patricia

A brand new dual-polarization-modulated complete chiroptical spectrophotometer (D-CCS) was efficiently developed for recording artifact-free chiroptical round dichroism (CD) and circularly polarized luminescence (CPL) spectra of optically anisotropic samples on the premise of the Stokes-Mueller matrix method. The D-CCS contains an extra second photoelastic modulator (PEM) set in entrance of the pattern and a second PEM… Continue reading
