The chemist noted that the two chlorines were geminal on the same carbon, affecting the molecule's reactivity.

Under the streetlamp, the cat cast a geminous shadow that seemed to follow it in step.

In her dialect, the /t/ is often pronounced geminately, creating a noticeably longer sound.

The artist placed the mirrored sculptures geminally on either side of the hall to create a sense of balance.

The research group synthesized several geminal diamines to investigate their reactivity in intramolecular cyclization reactions.

In aqueous solution, many aldehydes and ketones exist in equilibrium with their geminal diols.

The chemist isolated a geminal diol that had formed spontaneously in aqueous solution.

The chemist isolated a geminal diamine from the reaction mixture and characterized it by NMR and IR spectroscopy.
