High-Resolution Mass Spectrometry Analytical Chemistry & Spectroscopy Da Mass spectrometry capable of measuring mass to four or more decimal places, allowing molecular formulae to be determined.

HOMO and LUMO Chemical Bonding & Molecular Structure eV The highest occupied and lowest unoccupied molecular orbitals, which together govern a molecule's reactivity and spectroscopy. ΔE = E_LUMO − E_HOMO

Hydrate Foundations of Chemistry Dimensionless A crystalline compound in which a definite number of water molecules is incorporated into the lattice. MX·nH₂O

Hydrate Isomerism Inorganic & Coordination Chemistry Dimensionless Isomerism arising from water molecules occupying either the coordination sphere or lattice positions outside it.

Hydration Energy Solutions & Colligative Properties kJ/mol The energy released when one mole of gaseous ions is surrounded by water molecules to form a dilute aqueous solution. ΔH_hyd ∝ z / r

Halogens Atomic Structure & Periodicity Dimensionless The group 17 elements — fluorine through astatine — which are one electron short of a full outer shell. ns² np⁵

Heat Capacity at Constant Volume Thermochemistry & Thermodynamics J/(mol·K) The heat needed to raise a system's temperature by one kelvin while its volume is held fixed. C_V = (∂U/∂T)_V

Homogeneous Catalysis Chemical Kinetics & Catalysis Dimensionless Catalysis in which the catalyst is in the same phase as the reactants.

Homogeneous Mixture Foundations of Chemistry Dimensionless A mixture whose composition and properties are uniform throughout, with no visible boundary between the components.

Hückel's Rule Organic Chemistry Dimensionless The rule that a planar cyclic conjugated system is aromatic if it contains 4n + 2 pi electrons. 4n + 2 π electrons
