Michael Jackson of the University of Wisconsin-La Crosse is supported by a grant from the Experimental Physical Chemistry Program to investigate the high resolution absorption spectroscopy of a series of symmetric (fluromethane and phosphine) and asymmetric (sulfur dioxide, difluoroethylene, hydrazine and methanol) top molecules using far ir (FIR) Stark spectroscopy. Analysis of the spectra will yield frequencies of the many spectroscopic transitions, molecular structural parameters and accurate electric dipoles. In addition, measurements through the FIR region will give the rotational state dependence of doublet/inversion splitting and of the electric dipole moments.Molecular spectroscopy provides a way of both detecting and identifying molecules remotely and of determining their fundamental internal properties. This study extends the work into the infrared region of the spectrum where there are applications to molecule detection in interstellar space, planetary atmospheres and to laser science.

威斯康星大学拉克罗斯分校的迈克尔·杰克逊获得实验物理化学项目的资助，研究一系列对称（氟甲烷和磷化氢）和不对称（二氧化硫、二氟乙烯、肼和甲醇）的高分辨率吸收光谱使用远红外 (FIR) 斯塔克光谱分析顶级分子。 光谱分析将产生许多光谱跃迁的频率、分子结构参数和精确的电偶极子。 此外，通过 FIR 区域的测量将给出双峰/反转分裂和电偶极矩的旋转状态依赖性。分子光谱提供了一种远程检测和识别分子以及确定其基本内部特性的方法。 这项研究将工作扩展到光谱的红外区域，可应用于星际空间、行星大气和激光科学中的分子检测。
