How does the hydrogen bonding give changes to valence electrons?

利用远紫外衰减全反射光谱仪（ATR-FUV）研究了氢键和范德华力等分子间相互作用对价电子的影响。研制了用于低温（~-70℃）测量的ATR-FUV设备，对液体丙酮、固体烷烃和液体烷烃的ATR-FUV光谱进行了观测。通过对低温液体中电子态的计算结果与高能级量子化学计算结果的比较，我们对分子间相互作用对价电子的影响有了新的认识。

Effect of intermolecular interaction, such as hydrogen bonds and van der Waals forces to valence electrons were investigated by using an attenuated total reflection spectrometer in far-UV(ATR-FUV). After developing the ATR-FUV equipment for measurements in low temperature(～-70℃), ATR-FUV spectra of liquid acetone and, solid and liquid alkanes were observed. Comparing the results of electronic states in low-temperature liquids and high level quantum chemical calculations, we got a new insight about the effect of intermolecular interaction to valence electrons.
