Laser spectroscopy in jets is one of the main sources of structural data from molecular aggregates. Consequently, numerous and sophisticated experimental systems have been developed to extract precise information, which is usually interpreted in the light of quantum mechanical calculations. However, even with the most sophisticated experiments, it is sometimes difficult to interpret the experimental results. We present here the example of water dimer and how after almost 70 years, the assignment of its mass-resolved IR spectrum still generates controversy that extends toward the mechanism of ionization of water aggregates.
射流中的激光光谱学是分子聚集体结构数据的主要来源之一。因此，人们开发了众多精密的实验系统来提取精确信息，这些信息通常根据量子力学计算进行解释。然而，即使是最精密的实验，有时也难以解释实验结果。我们在此给出水二聚体的例子，以及在近70年后，其质量分辨红外光谱的归属如何仍引发争议，且这种争议延伸到了水聚集体的电离机制。
