Isom greeted each guest personally as they arrived at the gallery opening.

During the analysis, we discovered that the sample contained an isomer that exhibited markedly different reactivity despite sharing the same molecular formula.

The chemist explained how isomers can have identical formulas but different properties.

Isoms gathered on the porch every summer to share stories.

The metastable isomer persisted for hours before decaying to the ground state, allowing researchers to study its spin-dependent transition.

The chemist demonstrated that 1-butanol and its structural isomer behave differently under acidic conditions.

When analyzing the sample, the chemist discovered a positional isomer that explained the unexpected shift in reactivity.

In older textbooks, chemists often referred to either the cis or trans form of a molecule as a geometric isomer.

The optical isomer of the drug binds to receptors differently, producing distinct biological effects.

During the experiment, the team observed how a valence isomer rapidly converted into its more stable form when exposed to light.
