inversion

9.3
A chemical change that makes a substance rotate light the other way
  • noun
  • /ɪnˈvɜrʒən/

  • The chemist explained that the process of inversion is crucial for understanding how certain compounds exhibit different optical rotation behaviors.

Examples

  • The clinical implications of such chiral inversion in humans remain unclear.

    Academic text (1991)

  • Could stereoselective inversion be related to some forms of toxicity?

    Academic text (1991)

  • When that is the case, we're going to call that temperature the inversion temperature or T by NV.

  • Electrocardiogram showed T-wave inversion on the aVL, V5, and V6.

    Academic text (2007)

  • Population inversions in molecules such as OH, CH, methanol, and H2O produce strong natural maser emission.

    Academic text (1999)

  • For certain compounds, inversion can lead to significant changes in their chemical properties and how they interact with light.

  • The study focused on how inversion in molecular structure affects the optical activity of various substances.

Morphology

inversion = invert (semi-transparent) = invert + ion

Morphologically a nominalization of 'invert', but the chemistry sense (change in direction of optical rotation) is technical and not fully derivable by general knowledge.

Etymology

Inversion comes from the Latin invertere, where in- means 'in' and vertere means 'to turn'. In chemistry, an inversion is a 'turning' of how a substance rotates light, so the direction of rotation changes.
