<Molecular beams> are cool because they create a one dimensional flow of <molecules>, which makes it easier to observe certain single-molecule effects, as it removes the multi-particle issues from experiments.

Key <molecular beam> experiments include:
* <Stern-Gerlach experiment>, which confirmed the existence of <spin>
* <Rabi's NMR experiment>, which confirmed the existence of <nuclear spin>

The center piece of the control system of <atomic clocks> is a <molecular beam>.
