Abstract
The far-infrared region of the electromagnetic spectrum, informally defined as the wavelength region between 0.025 mm and 2.00 mm, is an area that has been investigated using laser radiation for more than 50 years. Research with far infrared lasers has a range of applications including terahertz imaging, a form of noninvasive imaging. Creating a catalog of far-infrared laser emissions is also beneficial for their use in high-resolution spectroscopic investigations of stable molecules and short-lived free radicals. The purpose of this research was to measure the frequencies of known far-infrared laser emissions generated by 13CD3OD, an isotopic form of methanol. This was achieved using an optically pumped molecular laser and two carbon dioxide reference lasers. In this work, the frequencies for 16 far-infrared laser emissions have been measured with a one-sigma uncertainty of approximately 0.7 MHz. This poster will cover the experimental procedure used for this research along with the data that were recorded.
