Chirped-pulse mmW spectroscopy in uniform flows

CPUF combines chirped-pulse Fourier-Transform mmWave rotational spectroscopy with uniform supersonic flows as a novel probe of dynamics and kinetics at low temperature. The power of the combination arises from the cooling of the nascent products to low and uniform temperature in the flow coupled with the nearly universal and quantitative detection my micro- and mmWave chirped-pulse spectroscopy.
