nuclear magnetic resonance method phase cycle A technique used in FT NMR experiments whereby the sense of application (or phase) of the rf pulses is altered on repeating the experiment such that addition of the resulting signals results in increased intensity for the signals of interest, elimination of artefacts and more effective noise reduction. phase sequence CHMO:0001879 2009-05-29T12:00:00Z https://orcid.org/0000-0001-5985-7429
