Implementation Of A Chirped Pulse Fourier Transform Microwave Concentration Lab Report
Implementation of a Chirped Pulse Fourier Transform Microwave (CP-FTMW) Spectrometer
Abstract:
Under the condition in which electric and magnetic fields are absent, rotational constants is a three molecular constants that substantiate polyatomic molecule. In this laboratory experiment at Missouri University of Science and Technology, we are going to collect rotational spectra by using 2 separate types of microwave spectrometers -- the FTMW (Fourier Transform Microwave) spectrometer and CP-FTMW (Chirped Pulse Fourier Transform Microwave) spectrometer.
Introduction:
FTMW (The Fourier Transform Microwave) spectrometer is a narrowband technique used to determine the structure of gas phase molecules. On the other hand, the CP-FTMW (Chirped Pulse Fourier Transform Microwave) spectrometer is a new technique created to allow for a broadband acquisition of the rotational spectra. …show more content…
In fact there are several factors affected the signals. For instance, the vacuum, which directly affect the pressure, and also the Width, which control the amount of gases put into the chamber. By adjusting them, we looked for the better signals.
Discussion:
The experimentation process was profitable, but the outcome was not as desirable as we expected. Therefore, we need to make some improvement in the future research.
In the future, we are going to improve the vacuum condition. (Current pressure of CP-FTMW spectrometer is about 1.6 x 10 - 5, while the pressure of FTMW spectrometer is about 3.3 x 10 - 6). Also, we are going to repair the heating element and add in a laser ablation module, by which we can study metal containing species. Lastly, we will increase the microwave pulses.
