分子束技术 meaning in English

molecular beam technique

In our experiments , these complexes , produced in supersonic beam expansions , are amenable to high resolution resonant two - photons ionization spectroscopy , which make it possible to obtain detailed information on their electronic - vibrational states . through resonant ionization spectra and together with time - of - flight mass spectrometry in supersonic molecular beam , the internal rotation for ch3 and intermolecular vibration for atom ar ( or n2 ) in the complexes ( c6h5ch3 . .
实验中采用了高分辨率的共振电离光谱技术和超声分子束技术，通过共振电离光谱和飞行时间质谱技术的手段探明了复合物c _ 6h _ 5ch _ 3 … n _ 2 、 ar的电子态、振动态以及甲基( ch _ 3 )内转动的详细情况。
