Rotational spectroscopy of iodobenzene and iodobenzene–neon with a direct digital 2–8GHz chirped-pulse Fourier transform microwave spectrometer

Multi-resonance effects within a single chirp in broadband rotational spectroscopy: The rapid adiabatic passage regime for benzonitrile

“…A setting of 6% gain was the maximum that could be used before portions of the chirp were too large in amplitude to be recorded by the oscilloscope. As described by Neill et al [9], the amplifier introduces spurious components, particularly the sidebands 2m(t) and 3m(t), with m(t) being the original chirp. These spurious parts are low in intensity relative to the primary chirp.…”

“…1 displays a scheme of our new chirped-pulse Fourier transform microwave spectrometer, COMPACT (compact-passage acquired coherence technique). It is a combination of the designs presented by Pate et al [1,9] and of that proposed by Grabow [7]. For experiment control, the program FTMW++ of Grabow (Leibniz-Universität Hannover) is employed.…”

Comprehensive analysis of the rotational spectrum of 2,2-dichloropropane

“…The older, cavity based, method of Balle and Flygare [7] is usually more sensitive and is endowed with higher resolution, but its relative intensity performance is poor. On the other hand application of the more recent chirped-pulse technique [28] operating on the same expansion plume, but along a different axis of the cavity, allows faster recording time and considerably better relative intensity performance [27,29].…”

Identification of Trace 2-Chloropropene with a New Chirped Pulse Microwave Spectrometer

“…The response signal is still very weak so that * corresponding author; e-mail: kisiel@ifpan.edu.pl averaging over many hours or days is necessary. The original chirped pulse spectrometer design has been refined further [10,11] in order to overcome various instrumental challenges and this enabled many spectacular studies, such as those of the small water clusters [11][12][13][14].…”
