Abstract
We used microwave spectroscopy to study 2,4,5-trifluorophenol for the first time. Microwave spectroscopy is used to find the shape of molecules. By finding patterns in the shapes of molecules, we can gain a better understanding of physical interactions at a molecular level. Our custom-built chirped-pulse Fourier transform microwave (CP-FTMW) spectrometer was used to measure the spectrum from 8 – 18 GHz. The spectrometer averaged 10,000 measurements of the spectrum to maximize the signal-to-noise ratio. We also used Gaussian 03W software to predict the rotational constants (shape) and distortion constants (flexibility) of the chemical. After a full analysis of the spectrum, the experimental spectroscopic constants will be determined.
