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大学的迈克尔·杰克逊（Michael Jackson）得到了实验性物理化学计划的赠款，该计划研究了一系列对称（氟甲烷和磷酸）和不对称（二氧化硫，二氟，二氟乙烯，氢氮醇和甲醇）的高分辨率吸收光谱法（二氧化硫），二氧化碳和非对称性。 光谱的分析将产生许多光谱过渡，分子结构参数和准确的电偶极子的频率。 此外，通过FIR区域的测量结果将给出双重/反转分裂和电偶极矩的旋转状态依赖性。分子光谱法提供了一种远程检测和确定分子的方法，并确定其基本内部特性。 这项研究将工作扩展到频谱的红外区域，在这些红外区域，在星际空间，行星气氛和激光科学中有分子检测的应用。
