Abstract

A system providing excitation and selective transport and/or reaction of isotopologues. Two or more isotope effects are combined within a reaction cell to produce transient differentiation of isotopologues through excitation or chemical reaction followed by rapid separation or conversion. A current conductor adjacent to a fluid carries an excitation current produced by a switching source. The excitation current produces an alternating magnetic field adjacent to the conductor that interacts with a population of isotopologues within the adjacent fluid layer to produce a population of reaction intermediates or products that have an isotopic composition different from the initial isotopologues. An electrolytic power supply may also be connected to the conductor to provide a voltage that may be used to selectively attract and electrolyze a portion of the reaction intermediates or products within the adjacent fluid layer.

Claims

exact text as granted — not AI-modified
1 . A system for spin modification of an electrolytic process, said system comprising:
