It is the goal of the proposed research program to develop a novel experiment, which will allow us to precisely determine the frequency difference of the two enantiomers of chiral molecules due to parity violation. The experiment will be based on state-of-the-art molecule-manipulation techniques, such as Alternating-Gradient focusing and deceleration, and high-resolution rotational spectroscopy. This would be the first experimental detection of this predicted very small effect. The precise knowledge of the energy differences between the molecular levels of the two enantiomers will not only help to answer important questions which relate to the homochirality of life, but it will also allow for important feedback for the existing and future theoretical methods developed to theoretically study and predict the effect.

提出的研究计划的目标是开发一种新的实验，这将使我们能够精确地确定手性分子的两种对映异构体由于宇称破坏而产生的频率差。该实验将基于最先进的分子操纵技术，如交替梯度聚焦和减速，以及高分辨率旋转光谱学。这将是第一次实验检测到这种预测的非常小的影响。两种对映异构体分子水平之间能量差异的精确知识不仅有助于回答与生命同手性相关的重要问题，而且还将为现有和未来的理论方法提供重要的反馈，以便从理论上研究和预测这种效应。
