摘要

设计了一种基于强大的超宽带微波源的实验装置，用于研究气态物质的吸收光谱。提出了一种测量物质吸收系数的方法。它是基于探测微波辐射通过所研究物质时光谱的变化，因此对入射辐射光谱的特征不太敏感。通过多次重复测量，精度进一步提高。研究了有机氟化合物C4F9I蒸气的旋转光谱。在所考虑的光谱范围内，在该化合物中观察到许多微波辐射吸收峰。

Experimental Method for Investigation of Rotational Spectra of Heavy Molecules at Their Interaction with the Microwave Field at Frequencies of 2–4 GHz

An experimental setup based on a powerful ultrawideband microwave source is devised to investigate absorption spectra of gaseous substances. A technique is developed for measuring the absorption coefficient of a substance. It is based on detection of a change in the spectrum of microwave radiation on its passing through the substance under study and is therefore low sensitive to features of the incident radiation spectrum. The accuracy is further increased by multiple repetition of measurements. Rotational spectra of organofluorine compound C₄F₉I vapor are investigated. In the spectral range under consideration, a number of microwave radiation absorption peaks are observed in this compound.
