Description

Title:A Low-cost Chirped-pulse Fourier Transform Microwave Spectrometer For Undergraduate Physical Chemistry Lab
Author(s):Carroll, Brandon
Contributor(s):Blake, Geoffrey; Finneran, Ian
Subject(s):Chirped pulse
Abstract:We present the design and construction of a simple and low-cost waveguide chirped pulse Fourier transform microwave (CP-FTMW) spectrometer suitable for gas-phase rotational spectroscopy experiments in undergraduate physical chemistry labs as well as graduate level research. The spectrometer operates with modest bandwidth, using phased locked loop (PLL) microwave sources and a direct digital synthesis (DDS) chirp source, making it an affordable for undergraduate labs. The performance of the instrument is benchmarked by acquiring the pure rotational spectrum of the J = 1 - 0 transition OCS and its isotopologues from 11-12.5 GHz.
