Abstract

It is noted that the chemical reactions occurring in rarefied cosmic clouds (molecular concentration less than or approximately to 10(2) cm-3) differ from similar laboratory reactions by the much greater effect on the outcome of external force fields. In this light it is hypothesized that the synthesis of optically active substances may occur in the outer space under the conjoint stereospecific effect of a magnetic and other molecule-orienting field. It is further conjectured that the optically active substances of the Solar System had been produced in the course of its formation out of the primal rarefield cloud.

摘要

值得注意的是，在稀薄宇宙云（分子浓度小于或约为10²厘米⁻³）中发生的化学反应与类似的实验室反应不同，外力场对反应结果的影响要大得多。据此推测，在外层空间中，在磁场和其他分子定向场的联合立体定向作用下，可能会发生旋光性物质的合成。进一步推测，太阳系的旋光性物质是在其由原始稀薄云形成的过程中产生的。
