DOI: 10.3390/molecules24071418
Abstract: This study investigated the measurement of circular dichroism (CD) spectra without controlling a phase modulator. In a conventional CD system, the peak retardation of the phase modulator must remain constant over the observed wavelength range.… read more here.
