Abstract

Nagy's report of an optical rotation of-0.023 degrees to -0.084 degrees in the Orgueil meteorite has not been confirmed. The highest rotation found in several fatty-acid and hydrocarbon fractions isolated from the meteorite was -0.002 degrees , less than that of optically inactive controls. The "rotations" observed by Nagy may have been caused by scattered depolarized light from colloidal particles, reduced instrument sensitivity due to low transmittance of the solutions, or a combination of both.

摘要

Nagy 报告说，奥格尔陨石的旋光度为-0.023 度至-0.084 度，但这一结果并未得到证实。从陨石中分离出的几种脂肪酸和碳氢化合物馏分的最高旋光度为-0.002 度，低于非旋光对照物。Nagy 观察到的“旋光度”可能是由胶体颗粒散射的去偏振光引起的，也可能是由于溶液的透光率低而降低了仪器的灵敏度，或者两者兼而有之。
