Mass-correlated rotational Raman spectra with high resolution, broad bandwidth, and absolute frequency accuracy [Applied Physical Sciences]

We present mass-correlated rotational alignment spectroscopy, based on the optical excitation of a coherent rotational quantum wave and the observation of temporal wave interferences in a mass spectrometer. Combined electronic and opto-mechanical delays increased the observation time and energy resolution by an order of magnitude compared with preceding time-domain measurements....
