A 2021 Chemistry World report says researchers used ultrafast electron diffraction to image and measure the complex before it separated, roughly 10 femtoseconds after forming.
What forms when water is ionised?
The reported transient species is a hydroxyl–hydronium complex: an OH radical associated with a hydronium ion (H3O+). Chemistry World described it as a radical–cation pair and wrote its composition as OH(H3O+).

This is a fleeting intermediate rather than a lasting molecular arrangement. The report’s account focuses on observing the pair during the brief interval before its components separate.
How long does the pair last?
The pair reportedly separates roughly one hundred quadrillionth of a second after formation—about 10 femtoseconds. This is an approximate timescale reported by Chemistry World on 12 October 2021, not a precise lifetime or an uncertainty range established here.

How was the fleeting structure observed?
The report identifies ultrafast electron diffraction as the technique used to image and measure the complex’s formation. In broad terms, electron diffraction can reveal structural information from how electrons scatter; here, its ultrafast use was described as capturing the transient pair before separation.
The available account does not establish the instrumentation configuration, experimental conditions, controls, or measurement uncertainties. The primary paper’s authors and journal details are likewise not verified here, so the specific findings and timescale should be understood as reported by Chemistry World, rather than independently confirmed details of the underlying study.
Rank #2
What the observation does—and does not—establish
The report presents a snapshot of an early event after water ionisation: formation of the OH(H3O+) radical–cation pair and its separation on an approximately 10-femtosecond timescale. The account available does not support extending that result to practical applications, biological effects, or broader claims about water chemistry.
