They discovered a first order phase transition, a discontinuity, in liquid hydrogen between a molecular state with low conductivity and a highly conductive atomic state.
他们发现了一个不连续的一级相变，这个相变是在液态氢低电导率的分子态和高电导率的原子态之间。

So molecular vibrations, you know, you've taken IR spectra they're typically on the order of 1,000 wave Numbers or so.
那么分子的振动，到了红外光谱的波段，它们通常大约有1,000个波数。

Studying circuits involved in a particular behavior has revealed much about the cellular and molecular changes that must occur in order to interpret the environment.
