A Circular Dichroism Spectrometer for the Vacuum Ultraviolet

Abstract
We have developed a circular dichroism spectrometer which will make measurements in the ultraviolet to 1350 Å. It is built primarily from commercially available components and is particularly simple in design. The instrument is linear and has a noise level over most of its range of less than 1×10−5 OD units for a 16 Å spectral slitwidth and 10 sec time constant. The absorption and circular dichroism spectra of (+) 3‐methylcyclopentanone to 1350 Å are presented.
