Ice and solid H₂S look as different as pears and oranges, leading Pauling to conclude that H₂O has hydrogen bonds and H₂S has van der Waals interactions. Now it is shown that the H₂S dimer, like the H₂O dimer, is indeed hydrogen‐bonded.

H2S二聚体是氢键结合的：通过微波光谱法直接确认

冰和固体H ₂ S看起来与梨和橘子不同，从而使鲍林得出结论，H ₂ O具有氢键，而H ₂ S具有范德华相互作用。现在表明，H ₂ S二聚体与H ₂ O二聚体确实是氢键结合的。
