Patent number: 9709485Abstract: A new technique which uses a pump-probe methodology to place a molecule into one or more excited rotational and/or vibrational states. By evaluating spectral changes due to at least one discrete frequency of pump photons a multi-dimensional characterization of the molecule's excited state energy level results. This multi-dimensional characterization typically involves evaluating the changes between excited and unexcited state measurements. The differential nature of the evaluation makes the technique self-referencing and solves problems common to many spectroscopic techniques. The multi-dimensionality of the technique provides high specificity and immunity to interferents. The preferred embodiments involve excitation by using photons suited to pumping the rotational states and evaluating the effects by probing the energy levels of one of more vibrational states.Type: GrantFiled: June 16, 2016Date of Patent: July 18, 2017Assignee: Kestrel CorporationInventors: Eugene W Butler, Timothy M Stratman, Boyd V Hunter, Paul Harrison, Jason M Cox
