“…The basic principle of the HAUP method is explained here; details of the principle of the original 3,14,15 and extended HAUP methods have been described in detail elsewhere. 6,11,16 The proposed HAUP system is shown in Figure 1. The CCD-HAUP employs a simple optical system that consists of only two optical elements: a polarizer (P) and an analyzer (A).…”

“…Because the value of p is independent of the sample setting, it has already been determined by a preceding experiment with an achiral crystal LiNbO 3 or MgF 2 ; using this procedure, HAUP measurements of various crystals have been successfully conducted. 6,11,12,17,18 For this study, the p value was determined as after mentioned by the wavelength dependence G-HAUP measurements of an achiral MgF 2 crystal. By assuming that k is dependent on λ and k = 0 in the wavelength regions, where the sample has no absorption, the optimum values of q, δY, and N are obtained by least-squares fittings using Eqs.…”

“…The extension of this method to the measurement of anisotropic colored materials has made possible the simultaneous measurement of LB, CB, LD and CD. [6][7][8][9][10] Recently, the HAUP apparatus has been generalized using a conventional Xe lamp and a monochromator to obtain ultraviolet (UV) and visible region spectra (300-680 nm); 11 monochromatic transmitted light is detected by a photomultiplier. Generalized HAUP (G-HAUP) has subsequently been applied to intercalated K 4 Nb 6 O 17 crystals with an azobenzene derivative, 11 and to laminated collagen membranes.…”

Fast-type high-accuracy universal polarimeter using charge-coupled device spectrometer

A fast, high-accuracy universal polarimeter was developed using a charge-coupled device (CCD) spectrometer (CCD-HAUP), to carry out simultaneous optical anisotropic (linear birefringence, LB; linear dichroism, LD) and chiroptical (circular birefringence, CB; circular dichroism, CD) measurements on single crystals without any pretreatment, in the visible region between 400–680 nm. The principle of the HAUP method is to measure the intensities of emergent light passing through a polarizer, a crystal sample, and then an analyzer, as the azimuth angles of the polarizer and analyzer are independently altered. The CCD-HAUP has the unique feature that white transmitted light intensity can be measured using a CCD spectrometer, compared with the generalized HAUP (G-HAUP) system in which monochromatic transmitted light is measured using a photomultiplier. The CCD-HAUP measurements across the entire wavelength region are completed within the G-HAUP measurement time for a single wavelength. The CCD-HAUP drastically reduces the measurement time for a dataset to only 1.5 h, from the 24 h required for the G-HAUP system. LB, LD, CB, and CD measurements of single crystals of α-quartz and enantiomeric photomechanical salicylidenephenylethylamines before, during, and after ultraviolet light irradiation show results comparable to those obtained using the G-HAUP system. The newly developed system is very effective for samples susceptible to degradation induced by external stimuli, such as light and heat.

“…As it was shown, serious experimental difficulties usually exist if one measures simultaneously different optical anisotropy parameters: optical activity (OA), LD, CD in optically birefringent crystals [7,8]. High-accuracy polarimetric methods represent the most precise and convenient techniques for solving the mentioned crystal optical problems.…”

Polarized absorption and linear dichroism spectra of chromium and manganese doped gallogermanate (Ca 3 Ga 2 Ge 4 O 14 ) crystals were measured and analyzed. Electronic transitions were identified and crystal field parameters have been determined. The value of linear dichroism obtained at the wavelength of 633 nm was compared with polarimetric measuring data for chromium doped Ca 3 Ga 2 Ge 4 O 14 crystals.
