Abstract: Fourier spectroscopy is used in the measurement of circular dichroism, the method involving the use of an interference polarization modulator which is characterized by production of negligible amplitude modulation in the absence of dichroism in the optical train that follows the modulator and in the detector. Either linear or circular dichroism in that region of the instrument will convert the polarization modulation into amplitude modulation. The polarization modulation is characterized by a different frequency for each wavelength of the radiation, thus the signals caused by the interaction of the radiation with dichroic sample may all be recorded simultaneously and may subsequently be ''''unscrambled'''' to derive the inverse Fourier transform of the ensemble of frequencies constituting the complete signal, and thus obtaining a transmission spectrum corresponding to the dichroism. The transmission spectrum in turn, in the case of the circular dichroism, may be converted into dichroism by dividing by the ordinary transmission spectrum (corresponding to ordinary absorption) which may be derived by ordinary Fourier spectroscopy.

Abstract: The method of making a glass electrode more sensitive to K than to Na in electrolytic solution includes the steps of forming a glass melt to have an initial composition of K2O, A12O3 and SiO2 where the mol percents of K2O and Al2O3 are chosen to optimize sensitivity ratio (K sensitivity to Na sensitivity) with low electrode output drift; digesting the melt for an extended period to substantially reduce the electrode output drift rate; and forming the electrode from the digest melt.

Abstract: Dichroism measurement apparatus includes interferometer means for processing linearly polarized source radiation to provide a beam characterized, for each wavelength, by ellipticity that alternates between left and right circular polarization and between which the beam polarization becomes linear in one direction as the ellipticity alternates from left to right circular polarization, and linear in the orthogonal direction as the ellipticity alternates from right to left circular polarization, the characteristic frequency Nu a of such alternation varying as a function of the wavelength. The interferometer means comprises relatively fixed and movable prisms, both having axes at 45* to the linear polarization direction, and actuating means for effecting such relative movement of said prisms to control the frequencies Nu a.
