Abstract

Examples herein include apparatus and techniques that can be used to perform rotational spectroscopy on gas-phase samples. Such techniques can include using a spectrometer providing frequency synthesis and pulse modulation to provide excitation (e.g., pump or probe pulses) of a gas-phase sample at mm-wave frequencies. Synthesis of such mm-wave frequencies can include use of a frequency multiplier, such as an active multiplier chain (AMC). A free induction decay (FID) elicited by the excitation or other time-domain information can be obtained from the sample, such as down-converted and digitized. A frequency domain representation of the digitized information, such as a Fourier transformed representation, can be used to provide a rotational spectrum.
