哥仑比亚大学用选择性地激发氯同位素的方法,已经生产了毫克数量级的几种浓缩氯化物。分离的办法是对一氯化碘加以单一光子激发。由于反应是在大容积中而不是在一束光中进行,可以予期反应将逐渐上升。浓缩是用带宽为三埃的染料澈光器完成的,因此进行这项研究工作的 Zare 说它是‘使人苦脑地粗制的’器件。如果带宽达到约0.1埃,就可以获得更大的浓缩百分数,因为在激发
Columbia University has used selective excitations of chlorine isotopes to produce several concentrated chlorides of the order of milligrams. The method of separation is single photon excitation of iodine monochloride. As the reaction is carried out in a large volume rather than in a beam of light, the response may gradually increase. Concentration was done using a dye-stripped spectrometer with a bandwidth of three angstroms, so Zare, who conducted the research, said it was ’hard-pressed’ devices. If the bandwidth reaches about 0.1 angstroms, a larger percentage of the concentrate can be obtained because of the excitation
