Chiroptical Measurement of Chiral Aggregates at
The centrifugal liquid membrane (CLM) cell has been utilized for chiroptical studies of liquid-liquid interfaces with a conventional circular dichroism (CD) spectropolarimeter. These studies required the characterization of optical properties of the rotating cylindrical CLM glass cell, which was used under the high speed rotation. In the present study, we have measured the circular and linear d...
متن کاملA microcomputer automated recording spectropolarimeter
MANY analytical laboratories have available minicomputers or microcomputer systems which routinely find use for data analysis. Recent trends have been toward applying computers not only for computational capabilities, but also for on-line control and data .acquisition from actual analytical instru-mentation. Numerous analytical instruments are being designed to incorporate a computer system as ...
متن کاملMicroscopic measurement of circular dichroism spectra.
A microscope device to measure the circular dichroism (CD) spectra of a specified microscopic region of chiral samples was constructed by combining of a couple of objective lenses and a CCD camera, which was installed in a sample chamber of a commercially available CD spectropolarimeter. By using this apparatus, high quality micro-CD spectra in the 60 x 60 microm region of samples could be meas...
متن کاملDifferential light-scattering of granal and agranal chloroplasts and their fragments.
Intact (class-A) granal and agranal maize chloroplasts and chloroplast fragments were examined for differential scattering of circularly polarized light (measured at 90 degrees) and c.d. (circular dichroism) (measured at 0 degrees) by using a modified spectropolarimeter with a large acceptance angle. Useful c.d. information was obtained by making corrections for scattered light. Chloroplast fra...

H and C NMR spectra were recorded with Bruker DPX-400, AVANCE-400 and DRX-500. The numbering of the protons relate to the numbering chosen in Fig. 1. High resolution mass spectra were obtained with a Micromass LCT via loop-mode injection from a Waters (Alliance 2695) HPLC system. Alternatively a Micromass Q-TOF in combination with a Waters Aquity Ultraperformance LC system was employed. Ionizat...
