A broadband Fourier transform microwave spectrometer based on chirped pulse excitation
Gordon G. Brown,Brian C. Dian,Kevin O. Douglass,Scott M. Geyer,Steven T. Shipman,Brooks H. Pate +5 more
TL;DR: The CP-FTMW spectrometer produces an equal sensitivity spectrum with a factor of 40 reduction in measurement time and a reduction in sample consumption by a factors of 20, and displays good intensity accuracy for both sample number density and rotational transition moment.
Journal ArticleDOI
Multiheterodyne spectroscopy with optical frequency combs generated from a continuous-wave laser
David A. Long,Adam J. Fleisher,Kevin O. Douglass,Stephen Maxwell,K. Bielska,Joseph T. Hodges,David F. Plusquellic +6 more
TL;DR: Dual-drive Mach-Zehnder modulators were utilized to produce power-leveled optical frequency combs (OFCs) from a continuous-wave laser, which allows for robust measurements of trace gas species and alleviates much of the cost and complexity associated with the use of femtosecond OFCs produced with mode-locked pulsed lasers.
Journal ArticleDOI
Measuring Picosecond Isomerization Kinetics via Broadband Microwave Spectroscopy
TL;DR: A broadband Fourier transform microwave spectrometer is developed that uses chirped-pulse excitation to measure a rotational spectrum in the 7- to 18.5-gigahertz range in a single shot and thereby reduces acquisition time sufficiently to couple molecular rotational spectroscopy with tunable laser excitation.
Journal ArticleDOI
The rotational spectrum of epifluorohydrin measured by chirped-pulse Fourier transform microwave spectroscopy
TL;DR: In this article, the rotational spectrum of epifluorohydrin measured by chirped-pulse Fourier transform microwave (CP-FTMW) spectroscopy is presented.
Journal ArticleDOI
Frequency-agile, rapid scanning spectroscopy
Gar-Wing Truong,Gar-Wing Truong,Kevin O. Douglass,Stephen Maxwell,R. D. van Zee,David F. Plusquellic,Joseph T. Hodges,David A. Long +7 more
TL;DR: In this paper, a frequency-agile, rapid scanning spectroscopy technique was proposed for fast and sensitive trace gas measurements and chemical kinetic studies, which requires no mechanical motion and provides a scanning rate of 8 kHz per cavity mode at a sensitivity of ∼2 × 10-12 cm-1 Hz-1/2, with a scanning range that exceeds 70 GHz.
