dissociation Usage Examples

Preposition: of

  • sensibility: I speak of the associative poet whose associative sensibility stands against the dissociation of sensibility.
  • molecule: Initial damage starts at the molecular level which can lead to dissociation of DNA molecules which in turn can lead to gene mutations.
  • water: An easy explanation for it is the ultraviolet dissociation of water.

Converse of object

  • involve: This in turn involves bond dissociation, gain of an electron by the halogen, and hydration of the halide ion.
  • imply: In some cases, effective reorganization can decrease task difficulty, implying a dissociation between frontal activity and basic memory demand.

Adjective modifier

  • collision-induced: For the removal of H atoms, the method of sustained off-resonance irradiation collision-induced dissociation ( SORI-CID ) in FT-ICR has been applied.
  • partial: If the effect is only one way we may call it a partial dissociation.
  • double: Consistent with the model, however, a sensitive psycholinguistic test, a lexical decision task, revealed a double dissociation between word groups.
  • functional: The transfer effect in artificial grammar learning: A functional dissociation between two modes of classification.
  • strong: Our results show a strong dissociation between two different tasks.
  • such: They seem to take both too seriously to allow such dissociation, and they want to use each for the enrichment of the other.

Modifies a noun

  • curve: The red line on the graph represents the dissociation curve at a normal pH ( pH = 7.4 ).
  • constant: Ionic equilibrium - acids, bases, dissociation constants, strength of acids, concept of pH.
  • dynamics: Our results have provided unprecedented insights into the dissociation dynamics of these molecules.
  • energy: In effect, it achieves its results by temporarily raising or lowering the bond dissociation energy.

Noun used with modifier

  • oxygen: Gaseous exchange at the tissues, partial pressure of gases, oxygen dissociation.
  • electron: We are using FT-ICR MS ( and specifically electron capture dissociation ) along with molecular modeling to probe their gas phase structures.
  • bond: In effect, it achieves its results by temporarily raising or lowering the bond dissociation energy.
dissociation Quotes

In the seventeenth century a dissociation of sensibility set in from which we have never recovered; and this dissociation, as isnatural, was dueto the influence of the two most powerful poets of the century, Milton and Dryden.
