Lithium fluoride molecular structure

For small molecules in the gaseous state, quadrupole coupling constants for deuterium and other nuclei can be determined from microwave spectroscopyS4,S6 and molecular beam resonance.43 For systems that behave differently in isolated molecules and in the condensed states, these techniques give unique information. Examples are lithium deuter-ide,61 which has an NaCl structure and therefore a zero field gradient for deuterium in the solid state, and deuterium fluoride,36 which forms strong hydrogen bonds in both the liquid and the solid state.
