ABSTRACT:
This invention relates to novel methods for affecting, and/or directing various crystal formation, structure formation or phase formation/phase change reaction pathways or systems by exposing one or more components in a holoreaction system to at least one spectral energy pattern. In a first aspect of the invention, at least one spectral energy pattern can be applied to a crystallization reaction system. In a second aspect of the invention, at least one spectral energy conditioning pattern can be applied to a conditioning reaction system. The spectral energy conditioning pattern can, for example, be applied at a separate location from the reaction vessel (e.g., in a conditioning reaction vessel) or can be applied in (or to) the reaction vessel, but prior to other (or all) crystallization reaction system participants being introduced into the reaction vessel.
