Physicists Just Captured The First-Ever Footage of a Molecule’s Spectacular Rotation
Imagine trying to film an event that was over and done within a mere 125 trillionths of a second. It’s something that molecular physicists have long been dreaming of, and at last it seems they’ve achieved their goal.

Will post reply when I get around to it.
Shouldn’t it be nanometreage, rather than footage?

most amusing
The first post had the addendum in square brackets which the forum software doesn’t print.
So I fixed it and posted an amended example of the first.
It will be known as the first amendment.
And probably the last.
Does anyone here understand this?
Eg. The article describes it as “strong-field-ionisation-induced Coulomb-explosion imaging”
“Even-Lavie valve operated at 250 Hz. After passing two skimmers, the collimated molecular beam entered the Stark deflector. The beam was dispersed according to quantum state by a strong inhomogeneous electric field with a nominal strength of ~200 kV/cm. Through a movable third skimmer, the molecular beam entered the spectrometer. Here, it was crossed at right angle by laser beams, where the height of the laser beams allowed to probe state-selected molecular ensembles, that is a practically pure rovibronic-ground-state sample of OCS”.

Sounds like complicated science stuff.

I wish they’d put it so simply in the original article.
