A Fast Digital Oscilloscope for Chirped Pulse Microwave Spectroscopy

2008年，啁啾脉冲傅立叶变换微波光谱学的发展，使超快电子技术的巨大进步成为可能，彻底改变了旋转光谱学领域。这种新方法使微波光谱研究具有数十个重原子的复杂分子系统成为可能，这在以前被认为是不可能的。特别有趣的例子是研究多达12个亚基的水团簇的结构、单糖的构象景观、手性识别事件和微观超流动性。我们于2011年在我们的实验室建造了这样的仪器，并于2012年进行了几次改进。从那时起，它已成为我们研究小组的主力，迄今已在高质量期刊上发表了12篇论文。

The development of chirped pulse Fourier transform microwave spectroscopy in 2008, made possible by the tremendous advances in ultrafast electronics, has revolutionized the field of rotational spectroscopy. This novel method enables microwave spectroscopic studies of complex molecular systems with tens of heavy atoms that were thought to be impossible before. Particularly interesting examples are studies of structures of water clusters with up to twelve subunits, conformational landscapes of monosaccharides, chirality recognition events, and microscopic superfluidity. We have constructed such an instrument in our laboratory in 2011 and implemented several improvements in 2012. Since then, it has become a workhorse for our research group and has resulted in 12 publications in high quality journals thus far.
